"Number of Uses" option for Subclass Feature Actions appears to be missing

I'm trying to implement the School of Lore Mastery subclass from UA.  At second level, this subclass grants an a ability that can be used once per short rest.  So that there will be a tracker for this in the character sheet, I have added an Action to the subclass Feature and am attempting to specify that there should be one use allowed per reset.

In doing so, I have discovered that the "number of uses" option described in the Add Action description field does not appear to be present.  Is this normal?  Did I break something?  Am I just being super oblivious?  The alleged "detailed limited usage information" also does not appear to actually exist.

save your action once in its current state, then click on edit, below the description, you'll find additional sections, for level scaling and limited use, there, you'll be able to select the number of uses of the feature, if it's a once per short rest feature, just type 1, or you can make it depend on an ability score or the proficiency bonus.

Hey, that worked.  Bizarre that they would put it in the description at the top and not even indicate that those options don't appear until after you've saved it.  Anyway, thanks!

It has to do with the workflow. The refresh condition has to be established before the uses can be.

So... I've gotten to the part where I can get the uses set up. I can only get either 1 or 5 for the number of uses depending on the stuff I have on. Like I have it using proficiency as +Addition it will give me 5 uses. (Prof +2, Character Level 1). If I do Prof xMultiply I get 1 use. The action editing has been pretty simple up to this point, just need it to be number of uses are equal to proficiency bonus. Which is where it has got me stuck now.
