Screenupdating doesn't work with multiple sheets

I have written a long code which calls other subs and I'm using the screenupdating set to false for each macro.
I define the sheets in the code with variable names to make it clearer in the coding when I'm switching worksheets.

Now, when I look to the Locals window, to the values for the different sheets involved, I find myself looking at the Screenupdating still set as True for the different sheets (see attachment).
I think that this is what causes my screen still to flicker, even when I specify at the beginning of the macro that the screenupdating needs to be false.

Does anybody knows how this can be solved?


Thanks
