First Q: Weird keywords in list
Hi,
My first question. I haven't found an answer to this anywhere.
LR version 9.3; Dell XPS Windows 10 ver. 10.0.18363 and using a 4T WD external hard drive for Lightroom photos.
After a false start I deleted all folders on the WD external hard drive, revamped my folders structure and re-imported all into a new catalog by folder structure (not date). So far, so good. But when I go to start adding keywords I find a whole list already there. And the names are weird and long - lots of yy yyy yy y with umlauts on each [see screenshot]. The question: how can I delete them all? [I can delete them one by one]. And, what are they; where did they cone from?

Thanks!!
