it would be nice if when i hit "load recommended" if it actually checked to see if i have any plays selected for a specific personnel set before it put it in the gameplan

this is specifically because i select the plays i want to use but am still getting used to setting up the gameplanning strategy for calling them so i like to see the recommended before i decide whether to make any adjustments and with it putting in personnel sets i don't even have plays selected for it throws me off...

also on a side note if i left it as is what would happen when they call for a personnel set i don't have any plays for?

The personnel/secondary/etc. gameplan actually just applies a weight to each play in the selection algorithm. So let's say you have:

Personnel 1 = 50%, 3 plays
Personnel 2 = 25%, 0 plays
Personnel 3 = 25%, 1 play

Basically the 2 plays in personnel 1 each have twice the likelihood of being selected as the play in personnel 3. Since you have no plays in personnel 2, you wouldn't have the ability to call a personnel 2 play.

You can see the likelihood of each play being called by clicking on the 'view plays' button below the quadrant. The larger the bar, the more likely that play will be called. This popup takes into consideration all of your current game plan settings for that quadrant against the selected plays in your playbook.

If you have no plays that apply (i.e. you only have plays of type Personnel 4 but that has a zero value in your game plan) then a play is randomly selected from your available plays.

So there is no harm in having the AI select personnel groupings for which you have no plays in your playbook as those would be ignored.
