Error Message:"the following parts have some elements without any section assigned"

[Mohamed Zied]

Hi,
I checked it many times, and there is no element without any section assigned. As you can see, the concerned parts are all green, if there was no section assigned, it would be grey. Moreover, the number of sets is equal to the number of sections assigned.
have anyone faced this problem before?
What can be the reasons?

Are you sure that these sets form whole parts ? Maybe there are some small regions where no set was defined and hence there’s no section assigned. Also make sure that proper element type is assigned to all parts and that there are no accidentally created features (e.g. wires).
