defective line spacing in forms

[architom]

There is an confusing behavior when filling forms (text field):

First, the line spacing is showing "normal" single spaced. This is the same in Acrobat and XChange Editor:

When I click in for edit line space goes to something like 1.5:

When activate "Highlight Fields" line spacing in all text boxes goes to 1.5:

How can I avoid this behavior?
Note: this behavior can't be found in Acrobat nor in browsers like Firefox, Chrome, Edge...

Hello, architom
Generally issues like this indicate that the form fields have a second, nonstandard set of data in place which is being improperly used by others. The Specification makes it fairly clear which set of data should be used, but many apps make exceptions in these areas, or choose to pull the "extraneous" data set under specific circumstances.

The only way we can address these cases, or determine if we should "follow suit" and mimic the handling of others is to look at such documents on a case-by-case basis. Along that line of thought, could I ask that you please send us a copy of this document, so that our Dev team can inspect it and see if a solution is available from our end.

Kind regards,

Thanks for your answer!

I can send you a copy of this document as this is an official form from our provincial government.
Is "Support@pdf-xchange.com" the right mailaddress for it?

Hello architom,

Yes - please send any sample files to support@pdf-xchange.com with a link back to this topic inside the mail as well, and we will take it from there!

Kind regards,
Stefan

p.s. We did receive the sample files and as a result a ticket was created in our internal system:
