Funny Error in the Designer

I am alone in my project, but now, the Designer seems to add everyone that are connected to the server


Could you share your project configuration from the gateway? Is it fair to assume none of these mystery users have a separate designer open?

On the gateway, Status -> Designer Sessions, we see all the designer opened in the right project

We have our HMI project. I will call them A and B
A and B inherit from project C that define Style Class in Perspective, and common HMI scripting class
C inherits from D that contains generic scripting package

I am alone in project A, there is 3 persons in project B
3 in project C, and we are 2 in project D
