Linear Repeat with Axis of Rotation

Hello

I'm currently having a problem with my linear repeat with a rotation axis.

When I create my repeat, the last element is not constrained. 

My question is: Why?

As the latter is not constrained, the following repetitions are not constrained either and everything moves.

Does anyone have a solution to my problem?

Under Sw2020 I can't find the problem, the last occurrence is constrained as normal
