API Level always 28

i have my own repo, whenever i run

fdroid update --clean

or add an app it usually gives me this:

WARNING: Requested API level XX is larger than maximum we have, returning API level 28 instead.

i ran

sdkmanager --sdk_root=“$ANDROID_HOME” “platforms;android-29” “platforms;android-30” “platforms;android-31” “platforms;android-32” “platforms;android-33”

and it still outputs the same thing which i thought would have fixed it, is there a fix for this?
