Move geometry point of complex element

Hello,

Thank you in advance with your help.

I used complex by element to complex two lines into one line.

My issue that is a gap occurred when I move point of this line as picture below:

Please help to guide me how to fix this issue for the existing complex line? Actually, I have one center line with a lot of location like that.

I want to make connection for this existing complex line, similar with "persist snap" or something like that, as well as I don't want to re-draw it.

Thank you so much with your help.
