ModelTable remains empty even if ollama models loaded.

[EricSolshkov]

First I noticed that all non-admin user have no model in their model list in front end. But I have several ollama models loaded, and visible to my admin account. Switch of each model in administrator settings is toggled active.
I tried toggle "Model Access" for 'default user' group and refresh. -> Failed, users still have no model visible.
I debugged in python and find in the main.py line 805, model_info = Models.get_model_by_id(model["id"]), the function returns None and additionally I tested Models.get_all_models() and get None as return.
The reason why models is visible to admin is that access filtering can be skipped if a user is admin.(main.py line 832 if user.role == "user" and not BYPASS_MODEL_ACCESS_CONTROL:)
I searched the project, and I find there is only one place Models.insert_new_model is called, where in the front end the + button is pushed. Does this mean checking model accessibility by calling Models.get_model-like functions will always return negative?
Is there any method to solve this except adding an environment variable "BYPASS_MODEL_ACCESS_CONTROL"?
