BUG - HogPC 3.14.0 - Cannot Assign Address to Custom Content Pixelmap Folder

Hi,

I am using a New Show on HogPC, 3.14.0

I added 300 RGB cells, and 10 Pixelmap layers.
I patched the RGB cells, and assigned their universes to outputs.

I can create a new folder in the Media Folder. 
I can add new media to the folder & use RENUMBER to set its Address.
I cannot use RENUMBER to set the Media Folder Address!
I can use it to change the addresses of the stock folders
I tried naming my new folder “008 Dan” but when I select my content (001) with the Media Picker, it also selects the Stock Content 001 in Stock folder 007
Can you investigate please?
happy to send showfile over.

Dan
