Required Validator in Inline data grid edit not working

Hello Radzen team,

The required validator in the grid column template is not firing. It was automatically added when the in line grid was created but it doesn't fire when the value is empty.

Based on this - RequiredValidator not working inside template
and Required Validator not working for text box - #3 by korchev
since there's no template form for the field in the grid column template, I tried adding one and still it didn't work.
With template form in the template

default format created by Radzen

First column is with template(I added) and 2nd without template.

Any help is appreciated

There is no Data assigned for the TemplateForm.

Added data, still not working.
