I'm fairly new to Houdini and I am probably aware that this is a simple fix, however I seem to be stuck in a rut! When trying to modify the muscle rigs stretch threshold and stretch compression it seems to be having no effect on the muscle. When looking further into this issue I noticed that my menu is very different to that of the menu displayed in siggraph 2017.

Image on the left is my machine, image on the right is a screen grab from Siggraph. I cannot seem to find the control tab in the flex menu set at all! I am unsure if this is a version issue. I am using Houdini 16.0.621!
hope this gets sorted soon.
I should add, this is the error message I am receiving when trying to set the compressed and stretched threshold
