Cannot delete unused material (sometimes, multiple unused materials)

Hello,

This happens very, very regularly. I will have a file where I stop using a material... and I cannot delete what appears in its place (once I delete my unused material). In it's place appears a material called:

• "Default material" (and its unused icon)

Then, when I rty and delete that unused material, a different unused material appears in its place called:

• "Default material 84" (aind its unused icon)

And each time I try and delete that unused material, it just counts up another unused material (... 85, ... 86, etc.). There are no meshes assigned to said unused material, it is just sitting there.

There are times where if I close the file and reopen it, I can delete the unused material... and there are times when, even after several times closing the file and opening it, the unused material cannot be deleted. There are also times when there are more than one of these unused material, that I cannot delete.

Anyone else running into this?
