Impossible to modify the ITEM scope when there is no longer a baseline set

Good morning,
I created an ITEMS scope then I created the baseline. I then deleted the baseline, when I modify a number in the ITEM scope or I want to assign CBS to scope ITEMS Here is the message I receive even though there is no longer a baseline: Original values cannot be changed for the scope item because the project baseline is set.
Even if there is no more baseline set
