ERROR Loop End - Active Scope End node in inactive branch not allowed

Hello All, Hope all of you are doing well.

I am using KNIME Ver 5.8.1 LTS, I am facing a problem, which I am not able to solve. I tried in forum but not found any suitable solution.

I am having 7 workflows in my project. First 5 workflows generating required data in in excel and all are running individually fine without any error.

6th workflow consolidating all output excels in to 1 it is also running individually fine and producing desired result.

7th workflow running all above mentation 6 workflows sequentially, after the 1st iteration i am getting error “ERROR Loop End Active Scope End node in inactive branch not allowed” which I am not able to solve.

Kindly Help me to solve it or suggest me the work around.
