Hi,
To attempt to reproduce the issue that you have reported I have performed the following steps in a launcher build of UE 5.5.4 :
- Import the provided FBX file with ‘Source Lightmap Index’ set to 1, ‘Destination Lightmap Index’ set to 1, ‘Min Lightmap Resolution’ set to 128 and ‘Generate Lightmap UVs’ disabled.
- Add the asset as Foliage via Foliage Mode
- Paint the Foliage asset onto a Landscape
- Build static lighting
- Save the map and close down the editor
- Re-open the editor
Following is a screen capture of my results:

I am currently unable to reproduce the results that you are experiencing. This could mean that our projects are out of sync, I have attached my test project for you to confirm the results at your end.
As a follow up question, does the issue still occur of you place the asset into a basic map with only a landscape and default lighting?
Kind Regards
