Looking closely at it, I think the text objects seem slightly offset from the base, so they don’t get printed flush on the plate. Check your first layer to see if the text appears in it. Since you’re printing the text on the plate side, it needs to be completely flush to the rest of the object or it will get printed into the air.
To see how the direct export to Bambu Studio or Orca works, check out this thread and look at the video in the announcement: 26.170 - Multicolor Support for Slicer Integrations from Visualization
I don’t know what functions are restricted in the free version, sorry.
PS: clean your print plate, I can see a fingerprint at the bottom right of the right one.
