Engines/SRB's do not show up in the staging overview

[Elsierd]

Hi all

I am having an issue where most of my engines/srb's do not show up in the staging overview. I have tried quite a lot but can't find the issue here. I do use RO/RSS and the only (engine) mods I've added are the EDB
mods. I use KSP version 1.8.1.

The most recent versions of RO are intended to be used in KSP 1.12.3, try using that version instead and see if that helps? If not, post a screenshot in the VAB and/or in flight and your logs please:

Which engines specifically aren't showing in the staging menu, or is it all of them?

Thanks for your answer @jimmymcgoochie. I use the RO version for KSP 1.8.1 so that should not be the problem. There are only few engines that show up, only some stock solid rocket boosters. All other stock and modded engines do not show up. I will try to post some screenshots and logs tomorrow when I get home.
