DevExpress style changes in Inventor

Multiple forms that i have look different inside Inventor compared to the DevExpress preview.

Preview: 

Style in Inventor:

And some other weird behaviour happens: when opening the Bill Of Material, all styles change again until i restart Inventor:

Does anybody know why this happens and what to do about it?

I want it to look like the preview.

I have no experience with DevExpress components, but it is used by Inventor internally. Try to look at this blog post for Inventor 2025 and similar posts for older versions, which version of DevExpress is used.

Try to use the same version as Inventor.

I am using 22.2.7 in Inventor 2025, which is the right version.
