I use a Nintex Form, but sometimes some fields are not shown properly. For example, in this case the Speaker field and Fixed Participants fields are broken/collapsed.
It's random, when it works and when it doesn't:
I tried using the custom CSS part in the Settings of Nintex Forms and tried things like:
.nf-form-input nf-section {height: 24px !important;}
, but it didn't change anything.
Any help is appreciated!
