Can't figure out where this -1 comes from

[Jankomatic]

This character is a gnome bard, we can't figure out how this -1 got on the char sheet for Con. Nothing in the background, ancestry etc is a negative that we can find. I don't see a way to even get rid of the negative.

That's had a temporary modifier added via CTRL+mouse-wheel. See the "temporary modifiers" line in the User Guide here: https://www.fantasygrounds.com/wiki/index.php/The_Basics#Number_Fields
