web ui is missing models

[thadude3]

When I "Analyze" the following unsloth/Qwen3.5-35B-A3B-GGUF, it shows that there are 21 files. When I look at the list of quantizations I see 17.
Specifically the following variant is missing Q4_K_XL, Even if I apply it to the filter it doesn't show up in the list. Is it possible XL is filtered or doesn't work?

Same in several unsloth repos.
I think it filters them out because they have UD in the name. Like Qwen3.5-27B-UD-Q4_K_XL.gguf
