Hi,
Edit: It appears that this is a Mac only bug
I am running Logos 5.2a Service Release 5 (5.2.1.0149), and discovered this accidentally when I was looking up the word Tartarus <Lemma = lbs/el/ταρταρόω>
To help recreate the problem consistently, I used the Bible Word Study Guide for the word "ταρταρόω" to open up each of the Lexicons under the Lemma section by clicking on the hyperlink (this is to ensure that I do not touch the Active Index "ταρταρόω" which appeared in the Reference box). I then click on the Parallel Resources Set (PRS) button for each of the Panel in the screen shot below.
All the lexicons on the top left quadrant of the screen shot work as expected, showing both my PRS "Lexicon Greek (21P)" and the system default PRS "All Parallel Resources"

I found that 3 Lexicons are not behaving as expected.
- DBL Greek
- Enhanced Strongs' Lexicon
- The New Strong's Dictionary of Hebrew and Greek Words
Noticed
- The system default PRS "All Parallel Resources" disappeared from the drop down list
- The list of "Lexicon Greek (21P)" is not complete compared to the top screen shot
- The list of "Lexicon Greek (21P)" included Resources that do not have a Greek Headword "ταρταρόω" (TDNT, Vine's Complete Expository Dictionary)

I also found another issue when I click on PRS button, with active "ταρταρόω" Greek headword of Mounce, the drop down list of my Hebrew PRS "Lexicon Hebrew (10P)" is shown (?) instead of the "All Parallel Resources" (Mounce is not in my PRS "Lexicon Greek (21P)")
