Guild Merchant doesn't seem to allow for Navigator's tools

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.
