There seems to bea bug in the latest version of the editor.
If you put IA buttons into groups e.g.
Amp channels - Group 1
OD/Dist pedals - Group 2
Mod pedals - Group 3
When you select a Preset on the Presets Page, 1 IA button from each group is selected by default and you can't deselect that group i.e. Amp channel selected, OD/Dist selected & Mod selected - you must use one button from each group. You have to go to the Buttons Page and set all IA buttons to: Group - None, then you can return to Presets and select the IA button combination that you want.
If you then reassign the groups you can go to Presets and any group that you haven't selected from remains unselected. If you then select an IA button from a previously unselected group, you can't then deselect from that group without first setting all IA buttons in that group to Group - None
