Keyword search keeps taking you back to first occurrence of that keyword in the list

When I enter a word in the search box of the keywords, it highlights all occurrences and when you hit the triangle button you scroll through them one at a time.  Unfortunately when I get to the occurrence I want and pause there, it automatically goes back to the first occurrence in the list unless I remember to clear the word out of the search box as soon as I get to the keyword section I want.  It is a very annoying thing that just started happening within the last few months.  I have a very extensive nested set of keywords I use and it is impractical for me to limit the occurrence of a word to only one place in the keyword list.  Anyone else experiencing this or have any ideas how to prevent this?  Thanks.

I have attached my system information.
