Import Export Visual Studio Errors

Question

I get 2 errors when importing (or exporting) parameters, but, unfortunately, is not very descriptive:

Error 1: Failed to export settings for '# 2015' [code 7366]

Error 2: Failed to export settings for '# 2001' [code 7366]

I suspect # 2001 and # 2015 are identifiers of some parameters.

Any ideas?
