H4 and h4 EAD different service center

Hi my h4 was applied along with H1(got approved under premium processing)In Aug 2021 h4 is still pending approval in Texas service center. Filed h4 EAD stand-alone in Dec 2021 but the service center for that is California. Has anyone come across this? Would there be a problem if the applications are in 2 different service center?

This is not an issue however in case if EAD gets processed before H4, they will want to see H4 approval first which can cause delay as they are in different processing centers. Next time apply both together that way they go to same processing center.
