Bug in Web App: BWS yields no results

Shalom,
I have encountered a problem with the Bible Word Study guide in the web app. Whenever I open a new BWS tab and select a Hebrew lemma from the drop down menu the guide takes a long time to load and eventually yields no results (except for the two links to do textual searches).
If I select a Greek lemma in the drop down menu or if I right click in the LHB to start a BWS everything works as expected (see the tab on the left in the screenshot below).
I think I have already discovered part of the problem: all of the Hebrew lemmas suggested in the drop down menu are based on the Westminster morphology (see the search tab on the right in the screenshot).
FYI: I am using the web app on my Android smartphone. LHB is my highest prioritized Bible.
