25%[Most editing locked] in simulink

25%[Most editing locked] . this is the pop-up I get in simulink after simulating and the thickness of waveforms is too much around 2mm instead of 0.1mm.

Why Am I getting like this in smulink and any solution for this?

Some of the blocks are giving the results(waveforms) with thick waveforms (like mixture of bubbles and thin line).

Can it be solved?

Why am I getting this ?

I also sometime in the last few months started getting the subject message, and it just recently change to "26% [Most editing locked]" (please see snip). I'd really like to know what the meaning is here.
