Bookmarks with new Button Slicer are broken after deploying through Power BI Deployment Pipeline

[AlenaT]

Dear Colleagues, 

I faced an issue that Bookmarks with new Button Slicer are broken after deploying through Power BI Deployment Pipeline.

Steps: 

1. A Bookmark is saved in Power BI Desktop and works as expected after publishing to Dev env: #1, #3 and #4 New Button Slicer visuals are selected (light blue color):

2. After deploying to Test env I can see that for the same bookmark, there are only #1 and #4 selected, #3 is not selected:

3. After deploying to Prod env I can see sometimes the expected behaviour: #1, #3 and #4 are selected, but sometimes it shows #1 and #3, but #4 is not selected.

It is really strange and unstable. As it didn't happen before with the old type of visuals, I can assume that this issue is related to the new Button slicer visual. 

Please help ASAP as it affects production! 

P.S. Please advise if there is any workaround to temporarily fix this issue until the permanent fix.
