Issue When Assigning a Location Using a Metadata Template

[PandDLong]

I use the Locations function in iMatch for frequent photo locations.  I often use a metadata template to manually assign the Location information to selected files  (most of my files do not have camera provided GPS).

I just had some situations where it didn't seem to work.  After some experiments, it appears to be setting tags that are empty AND emptying tags that have data.

I have attached screenshots of the geo-tags (the GPS tags are XMP:Exif and all others are the IPTC Extension Location Shown and Created tags as per the panel headers; the tag labelled "GPS Source' is mapped to an IPTC Extension tag that I have repurposed). 

The two screenshots are the different results each time I apply the template (a screenshot of it also attached).  The results of applying the template alternates between these two screenshots.

My starting situation had been as per the first screenshot where I had entered the Country manually many days prior. Then when I learned more particulars of this vintage 1936 photo, I applied the metadata template and got the result as per the 2nd screenshot.

I have been using Locations and templates in this manner for a few years but don't recall this problem happening before.  However, this situation where I partially enter information before applying the template may be new as I have just started doing vintage photos where information is determined in pieces.

A side note, you will see the autofill indicator on some tags.  That is something new that I have just started to try out but this location is not part of my test set but I did delete the autofill template as a further test and it made no difference to the above.
