Would also be very helpful if you could export the structure and post it here.

Tried it out and it looks like it's fixed in the newest pre-release. You will have to test it once it's out. Hope to release it the next two days.

almost the exact same problem on the version of the mod "Little Tikes_v1.5.0-pro 158_mc1.12.2"
Only the doors open fine, when I open them, but if they are opens someone else, I see the result just like in the screenshot above
