Keyword being deleted on export

[Megapenguin]

Hi there, I have encountered a very strange and specific problem. I make extensive use of keywords for managing my database, and one keyword I regularly use is 'siemens,' as in the electroics company. I recently noticed that some jpegs I had exported out of lightroom which should have contained this keyword, did not. I went back into the LR catalog, and 'siemens' is visible in the keywords there. I tried exporting again under various conditions, and without fail, the exported file contains all the other given keywords, but not 'siemens.' I've been doing this for a long time, and going back through my older images, I was able to establish that I had exported files containing this keyword succesfully until the end of October 2017. From that time on, 'siemens' does not appear as a keyword in any files I have exported, despite making hundreds of appearences in my Lightroom catalog. Any idea what's going on here? I can't find any info on non-permitted keywords. Is it related to being a brand name or something? Thanks.

Keywords can be set to not export. Did you check that? Right-click on the keyword in the keyword list to access its properties.

It wasn't that, but in checking for that I did discover the real problem! The keyword in question had somehow been set to be a 'person,' and my export settings were set to delete 'person' data. No idea how it ended up like that given I didn't know you could edit keyword properties. Anyway, we got there in the end - thankyou for sending me in the right direction!

One possibility is that in 2017, you accidentally entered "siemens" as the name of a face in People view or in Loupe  view. That would set the Person attribute of "siemens" (even if "siemens" already existed).
