[5e OGL] Bonus on Character Sheet not being Calculated Properly

I'm using the D&D5e OGL Character Sheet for a game I am playing. According to this   I have a 4 bonus to Constitution saving throws, however when I roll I get this:    Am I just reading this wrong? It says I get a +2, even though I should be get a +4. I'm new to D&D so if there's a rule I missed let me know.

This may be caused by an issue that can occur when switching over to the 5e OGL sheet from another Character Sheet (see the note in Adding the Character Sheet to a Campaign ). On the Attributes & Abilities Tab of the affected Characters, try locating and deleting all Attributes which have a name similar to: "PB" or "pb" " <skill> _bonus"; e.g. "deception_bonus" " <ability> _mod"; e.g. "strength_mod" To delete an Attribute, hover over it and press the x button that appears.

I noticed that if you update stuff [like level] while the sheet is "popped out" you get the old values in calculations.  If this might be your issue, simply undo the changes, and redo them, while the sheet it not "popped out".
