feedback master button states not being inherited by feedback layers

Hi there,

There's many issues and strange behaviors with the buttons in the feedback master.

Here's an exemple: This is how my button "Continue" looks like in the feedback master viewer - Only a subtle variation of color on mouse hover.

Then, my button looks like that in the project (after refreshing the feedback layout) :

Note:  this is the best result I got after trying again and again many differents solutions (sometime hover and down states are gradient blue, sometimes there's a big outline popping from nowhere with transparent bg color, or sometimes, why not, the button resize itself, etc.). Then, when I preview my slide, my custom button just don't work (no states change)...

I really don't understand what's happening between the feedback master button and project feedback button. But I wanted to try something else then. Why not creating my own button from a placeholder textbox?  Here's the result in feedback master viewer...

I can't change the state of my homemade button in the feedback master viewer. Why? From there, I tried many others things (like placing the button 99% transparent over the rectangle shape and trigger hover to change the rectangle color), but all I got is unpredictable behavior or software crash. 

So my final solution is to create a custom textbox and copy/paste it in each feedback slide of my project, which is really annoying (when it works, because the software crash almost each time I copy/paste). 

And before you ask, yes I will contact supprot team. I just wanted to add information to this forum thread. But if you have any idea how to create a custom button without a headache, I'll take it.

Thanks,

David
