Issue Description

Description

Currently, experimental form variations are broken. I have not noted when this started to happen, but when checking the contact/GDPR variations, it will not change.

There are two problems here:

The variations system is not orthodox. I would add a future iteration to be similar to the columns block
There is a temporary problem here that needs fix (I will send a PR to fix this for now).
