Multiple duplicate files listed after adding library files

What’s this about?

After adding the SharpMem files to use my Sharp Memory Display…
-> three Adafruit_SharpMem.cpp and .h files. I’ve found that if I try to delete one pane, it deletes all panes.

Looks like it’s been reported before: https://community.particle.io/t/tabs-are-duplicated-in-build/7690/6 and https://community.particle.io/t/web-ide-bug-new-multiple-files-feature-is-duplicating-things/2692

I’ll just move to developing locally using Particle Dev. Works a treat.
