Hey,
there are layout issues after updating to ACF PRO 5.5.6..
Look at this screenshot. With 5.5.5. everything was fine.

@acf-support can you confirm with this?
I’ve set up a field group that looks similar to yours, but I don’t see this. What I get is your 5.5.5 shot.
Is it still happening in 5.5.7?
@hube2 oh so sorry, I’m confused. I meant the 5.5.7.
version.
Can you confirm with this issue at the version 5.5.7. ?
I asked because that’s the version that I’m using. No, I see it the way it’s supposed to be shown and I’m not seeing any issues in the layout.
@hube2 I have tested this on an other WordPress installation and I get the same issue after updating from 5.5.5. to 5.5.7. There is really a bug of the layout. What can we do?
I can get you a json file of this field group and you can import this and test it on your installation?
I can look at your field group if you attach the json here. You’ll need to put it in a .zip to attach it.
I was able to reproduce this, but only if there is a true/false field as the first field in the second tab with tabs left aligned.
Please open a new support ticket https://support.advancedcustomfields.com/new-ticket/ and reference this topic.
Attached is a minimalist field group that duplicates the problem
@hube2 Thank’s for testing. I have added a new ticket.
