I have the problem, that I use different post types, I connect via the Relations Field. I use ACF Pro in the latest version. When I connect an Item it seems to kill the content of that connected items other fields. (Not all of them, but some). For example it kills the selection of radio buttons and Repeater Content.
Then I have to go to that object and update again for the content to work again.
For example in the backend of that object the right radio button seems to be chosen, but the Front End behaves, like I resetted it.
Content, which was in Repeaters is gone completely.
