Classifying model using labeled images error

this is the detailed workflow

I ran SAM to auto-segment every image, then used OPENAI CLIP to label each mask with ~30 construction classes (crane, gravel, scaffolding, …).
All masks were filtered, duplicates merged (largest‐area kept), renamed according to the RC requirements, and forced to single-channel 24-bit.
and the issue i am facing right now is that after following these steps 1) aligning images, 2) creating mesh with normal detail 3) Texturising the model.
when i try to import all the labels nothing shows up
on the other side when i only upload the labels individually it does show the classification but as soon as i increase the number of input label images
the classification starts to disappear
