Strange resizing of Text+ in Fusion composition -

Hey everyone, I have a Fusion composition with some animated graphics and some animated Text+ nodes. When I use this composition in a 1080p timeline in die Edit page everything looks fine. But once I drag it into a 4K timeline, the text gets scaled up, while the tracking and line spacing seem to be reduced. So the letters are overlapping. The graphics (which are an imported SVG) have the correct sizing. I just started using Fusion and have read some times that it may behave strange if a composition is put into timelines with different resolutions. So what I really cannot understand is that within the same composition some elements have the correct size in the Edit page and some don't. Has anyone ever had this issue and is there an easy workaround?

If this was After Effects I would just precompose which helps with a lot of issues but I have no idea what I can do in Fusion ...

Thank you!
