I'm unable to duplicate this issue using the same style and setting the drums to half-time - fills play before each part marker, however due to how Realdrums work they technically begin 2 bars before each part marker. It's possible that fills wouldn't work if you had less than 4 bars between each part marker, however it doesn't look like you do.

Right click on each part marker and check if "Allow drum fill..." is enabled for each one - it may be that you disabled one fill, then copied some bars around which propagated that to other spots. Otherwise, as others have mentioned, it would be best if we could take a look at the song file. Uploading to cloud storage would be best, however you can also email it to us at support@pgmusic.com and I'll take a look.
