Design Problem with multiple line fields

I have a problem with our design of the plumsail helpdesk. There is a big white space between some of the multiple line fields. I had a similar problem before with all of our fields but that got fixed with your help. You sent me this code which worked for most of the fields.

.fd-form .fd-grid > .row:not(:last-child) {
margin-bottom: 0;

.fd-form .fd-grid > .row:not(:last-child) > div > div > div {
margin-bottom: 1rem;

Now i have the problems only in the sharepoint helpdesk and not in the sharepoint online helpdesk.

I hope you can help me.

Best regards

Hello David! Could you clarify what platform you use: is it SharePoint on-premises or SharePoint Online? The screenshot looks like it is SharePoint Online because only for it we support modern UI.
