Long time issue of LR modifying keywords I enter
I have been trying to get an answer to this issue of over 10 years, so here I go again- sometimes when I add a keyword to an image(s) in Lightroom Classic (and before LR, in Bridge), I see it, but then pretty quickly afterwards, it changes what I entered, adding extra information, based on an older image I keyworded maybe 15 or more years ago in Bridge.
So, when I enter Reflection, see it in there…

But a moment later, LR has added all of this extraneous information.

This happens with many other keywords that I add, that I used to have set up in a hierarchy in Bridge a long time ago, before LR came along.
When I go to Keyword List in LR, and type Refection, this is what it shows.

I have Auto-complete text in the Keyword Tags field turned off in Interface preferences.
I am sure there is a simple way to stop this from happening, but I have been unable to figure it out, nor can anyone else give me an answer.
I am running LR Classic 10.4, macOS 10.14.6.
Thanks.
