Since yesterday evening, I have noticed that all slices that have and are using variations do not save properly and revert automatically to the default variation with all data values blank. Currently using the latest slicemachine version.
It does save for the first time and builds with that latest save but as soon as you change data somewhere else in that document, you will need to re-enter the data for that slice variation since the slice is reverted to default with no data showing.
Here is an example of what I want with a variation
Keep in mind though I'm filling data in the video it happens even without entering data, I'm inserting some values so its very clear the slice is not saved.
Mine is pretty much the same as @carribas screen recording. After saving/publishing, it no longer shows as the variation input, and reverts a default with missing data.
