A bug when creating categories using PUT: flow/global

The palette is bugged when creating categories in this format:

string + numeric (e.g. category name 1-1-1, or category name 1_1_1, or category name111)

For example, this is my request payload (category "test scenario1-1-1"):

The generated palette in Node-RED would be:

And when manually modifying one subflow's category to:

"test scenario 1-1-1"

The change is successful, and then the previous "correct" category pops up:

Another weird thing is that I could not update the bugged out category to the supposed correct category; the palette does not update.

Any thoughts on how to fix/achieve this?
