Is there a limit to the number of actions I can have or am I doing something wrong?

I use actions everyday at my job. Currently I have 15 actions saved that I use all the time. I have them all linked to the function keys. 11 of them use just a function key and 4 use shift + function. I have been trying to make a new action but I cannot get it to work at all. Its a simple action to round the corners of a rectangle to .05. I have a similar action that does the same thing but rounds them to .1. I made a graphic style for both and the action just places that graphic style on the rectangle. I've been using the .1 action for years now. I had orginally set the new action to use shift + f10, but it wouldn't work. I then tried shift +f9, f8 and still nothing. All of my other actions work perfectly and I've been using them for several years. The crazy thing is that I can highlight the action and press play from the action window and it works. Could it be the latest version of illustrator (27.2)?
