Button Slicer Format not keeping

[Schell]

Today my users of a Power Bi application I build complained that the button 'looks off'. I use the Button Slicer in Power Bi, I format it to not use the callout value in the button but a label instead. In the Desktop version, no changes to this visual have been made. In the Web version, and the app, the format turned the callout value on distorting the button.

I was able to correct this by editing in the web version and turning the callout value off then saving to match the desktop version. I ran a test and republished from the desktop and the callout value reset to on. 

Is there a resolution to this action, I think its a recent bug.

Facing same issue. Even if I modify button slicer on PowerBi web application and save, it is not retained.
