Transformation Warning

With the upgrade to 3.4, I have started to receive a "Transformation Warning" message when I open the Parcel Fabric. The "Learn more" prompt takes me to an "Install supplementary coordinate system files" page. These files have been installed to the default location, as directed, but the Warning message continues. 

Has anyone successfully navigated this issue? I have not treated them as an Add-in.

I don't have any experience with Parcel Fabric, but in general editing in Pro, I've noticed a weird issue where the horizontal coordinate systems are identical, but one has a vertical coordinate system, and the second is null.

Pro treats these as if they're wholly separate coordinate systems, and I have to explicitly choose "Do Not Transform" to get it to stop yelling at me.

Maybe there's something similar for Parcel Fabric, as of 3.4?

Thank you for the good lead. I had added a TIFF of a highway plan sheet to my map containing a Parcel Fabric because the deed contained no description except to say look at the plan sheet. I digitized the parcel polygon but never removed the TIFF. Unbeknownst to me, the coordinate system of the map changed to match the TIFF which I had never considered to be a possibility. Using the following BLOG entry, I changed the XY and Z coordinate systems back to what they originally were plus removed the offending TIFF. No more warning messages now.

Transformation warning: What does it mean and what should I do?

Thank you for the good lead. I had added a TIFF of a highway project plan sheet to my map to digitize a parcel polygon whose deed said look at a project plan sheet. Unbeknownst to me, this addition of the TIFF changed the coordinate system of my map which I did not consider as a possibility. I followed the directions of a July 26, 2021, BLOG entry to make the correction:

Transformation warning: What does it mean and what should I do?

Resetting the XY and Z coordinate systems back to what they both previously were shut down the warning message.
