Thank you for the model and explanation. I can reproduce the issue with your model in R2021a. Also, as you mentioned, it is not reproducible in recent releases of MATLAB.

It is highly possible that this has been a bug but fixed after R2021a. MathWorks does fix bugs and publishes "updates" for each release. However, as far as I know, R2021a is done with updates with R2021a Update 8.

In this case, I don't think there can be workarounds for R2021a other than updating MATLAB to recent releases.

There can be patches that development team can provide. If you insist to use R2021a, you can reach out to technical support and ask for it. However, I cannot guarantee for patch files because some issues cannot be fixed only with patches.
