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> _save_bonus"; e.g. "wisdom_save_bonus" " <ability> _mod"; e.g. "strength_mod" To delete an Attribute, hover over it and press the x button that appears.
