Hello Kirk,
On opening, first search in Filter, it works without problem.
These two problems persist after closing the Filter tab, doing a new search in Filter with other tabs open, 3 tabs for my example.
You close the Filter tab and click on a keyword, the keyword turns blue (and the photos are displayed, ok) ... if you click twice or double click on it, it is the one located 12 positions higher which is selected and the photos attached to this keyword.
Second problem, on the 1st click on another keyword the first remains blue and the second is surrounded by white, forced to click a second time to select the keyword
