Guild Artisan and Guild Merchants Backgrounds are combined on the character sheet.  

Unfortunately, the Artisan Tool list lacks the Navigator's Tools necessary for the Guild Merchant variant.

I have players that cannot properly configure their background.  Am I missing something?  Or is this simply a bug?

Thanks

I never noticed that. I wonder what other variant backgrounds they don't actually support.

Huh, apparently, one of the knight's retainers is a squire with the noble stat block.

Investigator should have proficiency in investigation (go figure) instead of the city watch's athletics.

I think it is just these 3 (really, 2 and a half) background variants that are not supported, the rest seem fine.
