Gene pool bug from grasshopper 0.9 to 1.0

Hi guys,
I found a very weird behaviour opening a gh definition from 0.9 to the gh 1.0 on rhino 6.

The gene pool component fails to collect data, it took me a while to understand that the problem ( i think) is in the overall definition not on specific component, if I test the components individually included the Gene pool, everything is working fine. Using a series of slider instead of gene pool solved the issue by the way.

I made a short video to explain the problem.

I wonder if this kind of behaviour could happen on any of my rhino 5 gh 0.9 files when I open them in gh 1.0 on a rhino 6 ? Any similar experience from gh 0.9 to 1.0 components?
