Clusters do not Recalculate in Rhino7

I also had trouble with updating content within clusters.
Using a Python component from the following post seems to sort that out.
Check 201218_RecomputeSolution_slider.gh in https://discourse.mcneel.com/t/rhino-precompute-grasshopper-python-script/114713/5

It is not fully automatic but only a click away.
Please let me know if it helps.
