Capo Error in Bb

Whenever I try to Capo 1 on a song in Bb it either says "An error occurred while downloading song content" or "Bad request - 'key G#' is invalid" in red lettering.
I don't know if this is an issue with Charts or Chordpro, but I'd love for it to be fixed, thanks.

Same issue here, Only happen with "Charts" on Web.
I found all with Capo and make the key show in "A" key will cause this error. eg: B-Original with Capo 2, C-Original with Capo 3, D-Original with Capo 5

Thank you both for the report, we'll have this fix deployed today.
