Scoryboard does not warn you about either of these. Both are things you can see on the Schedule tab once you know what to look for.
Why fixtures clash
Two fixtures clash when they share a kick-off time and a pitch, or when one team is needed in both at once.
Open the tournament and select Schedule.
Read the kick-off times down the group. If they are all the same, every match is meant to start at once.
Select BULK MATCH UPDATE and look at Same start time per round. If it is ticked, that is the cause.
Clear the tick box. Duration and Time between matches become editable.
Set a duration and a gap, then select Update Matches.
A football group has no rounds, so the whole group counts as one round. Leaving that box ticked puts every fixture on one kick-off time. It is ticked by default, and while it is ticked you cannot set a gap - which is why this is easy to do by accident.
A second cause, on the Format tab
A Group phase only tournament has a League schedule block on its format. Its Matches per week (optional) box says how many fixtures a week holds.
Each week's fixtures are shared out across the days you ticked and the pitches you have. Ask for more matches a week than those slots hold, and the extra fixtures stack. They land on the same day, at the same kick-off time, on the same pitch.
Two a week, one ticked day, one pitch: two matches at once on pitch 1.
Three a week on the same settings: three at once, and one team is then in two of them.
Raise Number of pitches/venues, tick another day, or empty the box, then save. Two pitches and two matches a week put the two fixtures on pitch 1 and pitch 2. Saving rebuilds every fixture in the tournament, so do it before any match is played. See Choosing a format for a football tournament.
Why a fixture shows only one team
A fixture with one team reads Away Team or Home Team on the empty side, and its status is Incomplete instead of Scheduled.
Find the fixture on Schedule.
Select Format and look at the group it belongs to. A free slot shows an Add Team row under the teams.
Either add the missing team, or open the group's Edit and lower its Number of teams to match.
The group has more slots than teams. Every fixture the empty slot is drawn into has nobody on one side. Filling the slot or lowering the count rebuilds the group's fixtures.
If it does not work
The times are fine but two groups overlap. Each group is scheduled on its own. Re-time the second group to start after the first.
Two matches share a time on purpose. If you have more than one pitch, set a Pitch number on each so it is clear they are not on the same one.
The fixtures double up week after week, under WEEK headings. This is a Group phase only tournament, and Matches per week is higher than your days and pitches hold - see A second cause, on the Format tab.
Lowering the team count deleted results. Changing a group's size rebuilds its fixtures. Do it before any match is played.
This is a padel tournament. Matches sharing a start time is normal there - see "Why padel matches share a start time, and when that is a clash".
