AutOptimize 'generatepress_child/style.css' not excluding ??

Good afternoon team,

I've got a bit of an odd one here... I can't figure out why 'generatepress_child/style.css' file is not being excluded from autoptimize when all other files I have in the settings are being excluded just fine.

Is is potentially because of the priority at which it's being called?

to replicate the issue:

add some custom css into generatepress_child/style.css file
go to Autoptimize settings > CSS Options
- Optimize CSS Code? : yes
- Aggregate CSS-files? : yes
- Also aggregate inline CSS? : no
- Generate data: URIs for images? : no
- Inline and Defer CSS? : yes
- Inline all CSS? : no
- Exclude CSS from Autoptimize: generatepress_child/style.css
save changes and empty cache

Notice how the generatepress_child/style.css file is still being caught in the aggregated autoptimize settings.

Any idea?
