@sparky619 I can see that. It's very strange.
On your first screenshot you do have the text of only being able to compete once a day. It's just not there on the competition itself.
Usually in the troubleshooting process, I try to gather some info to see if there's any rhyme why something happens. Since it was fine for me and then suddenly it wasn't, I tried to find a reason for that (aka higher riding skill for example meaning, the riding skill has some bug that unlocks everything).
But the problem is that the whole GUI unlocks when you can't participate (currently trying second horse theory) and that is confusing.
EDIT
So I tested a second horse and that's what the GUI looks like right after my first horse particiapated
So it seems the GUI adjusts according to available horses and if there is no available horse, it just unlocks everything. Maybe locking everything would be better.
Still don't understand why you only have half the text See beginning of this post.
Also tested a family with no horse and they have the same. All unlocked but since no horse, they can't participate.
