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 ?
