The global resources refuse to save regardless of times it has been set. While being quite of a nuisance it isn't game breaking. I haven't seen it mentioned so thought it better to mention in case it relates to another underlying issue.
I have experienced this across all bedrock platforms such as Android and Xbox.

This is still an issue. Just experience one of the many Minecraft crashes (that were suppose to be fixed) and your selected resource packs chose in global resources need to be reselected just adding to the aggravation of crashing in the first place.
