Incorrect behaviour when grouping empty fields


I use grouping based on a Multiple Select field.
Some values are empty (no selection in Multiple Select field) and some have values.
Grouping works fine.

But when unselecting a value in the Multiple Select fiels (unchecking a value), the grouping isn’t correct anymore. Fields that were initial empty are presented as “Empty value”, fields which had a value and are unselected are presented as “” and arent grouped together with the initial empty fields.
See screenshot.

This looks like a bug, can you please take a look at this?

thanks !
