This isn't unexpected. ~LABEL and ~LABEL~ are not the same label even
though they may look the same.

It seems to me the ERC is doing it's job as expect.

I would prefer not to strip anything off my labels. The trailing ~ in
you hypothetical example is unnecessary. Either Eeschema should
complain about an invalid label or it should display the all ~s but the
first one. Maybe we should prevent users from getting too creative with
their label naming. I'm not sure how serious this problem is given that
the ERC does the correct thing.
