PGLS

I just started playing one of the tournies (PGA 9) after a long absence. I play as Tour Pro. When I play the tourney, my clubs are different than when I play for fun, etc. Is there an explanation for this? Thank you.

i have had mine switch before, don't know why this happens but it does

The Perfect Golf API has no control over the players clubs.

Whatever you choose club wise for your players via "PLAYERS" in-game will all be available for any of the PGLS tournies.

Only thing I can think of is 2 Player profiles?

Here's some screenies of what I'm referring to:
1) Tour Player Settings - Clubs
2) Tour Player Settings - Fun, Practice, etc. (note 5 Iron)
3) Tour Player Setting - PGA 9 Tournament (note 6 Iron)

Kimmer (TP), which I will assume is your Tour Pro player, you used on the Practice Round and the clubs look correct when checked with the highlighted player in your 3rd screenshot.

First image you used a player called "Kimmer1947".
