when I try creating a new event from my frontend I do get a group drop down to choose from, but it only shows the 20 last created groups, not all of them. (There are 24 at this point.)
To test this issue I created a new group and sure enough the whole drop down row moved by one group.
Here are my stats
Events Manager 5.5.1
This should probably be quite easy to fix, but I couldn't find any limitation to 20 items in the code.
Could you please point me in the right direction, so I can fix this myself until an updated fixed version comes out?
