No worries. This appears to be a known bug in Beamer. See, for instance, 
the accepted answer here 
<https://tex.stackexchange.com/questions/489660/beamer-citing-distinct-works-outputs-the-same-reference-label>. 
You can work around it by setting the overlay specification on the first 
item rather than on the frame. See the attached LyX file, which I 
modified. (I also had to change the bibliography style, since I do not 
have the .bst file you are using, but that should be unrelated to the 
itemization fix.)
