Validation feedback - Does not show on Form

Hello,

I have made a microflow to validate if all required fields are filled.

This microflow is triggerd in the general Save Microflow and returns a 1 or 0 . If 0 the microflow exits if 1 it Commits.

If the 0 returns, de Validation Feedback messages should be shown beneeth the specified widgets on the form.

Problem:

On 1 form (Dataview)  these Validation Feedback messages are shown, on another form Dataview of the Same Entity, nothing appears when a 0 returns (Same Microflow's) 

What could I be doing wrong ? 

Thanks !
