Note Composer Fails to Merge when Properties are Present

WIthin a vault, I have some notes that have YAML front matter properties and others that do not. When I try to merge these notes using Composer Merge, the notest that have YAML properties are missing from the merged note. The notes that do NOT have YAML properties merge correctly.

Any ideas what could be causing this?

What I’m trying to do

I’m trying to merge notes, some with YAML properties, and others without.

I want to be able to merge notes that contain YAML properties.

Things I have tried

I deleted YAML properties from some notes. They correctly merged while the notes that still had properties did not merge correctly.

Note Composer, merge fails when YAML properties are present

Do the properties have any errors that you might have overlooked because using Source Mode?
