The screenshot below shows two Bible Word Study guides for the word δύναμις. The one of the left was run by right-clicking on the word 'power' in Acts 4:33, selecting the lemma and running the BWS. The one on the right was run from the guides menu, and typing g:dunamis into the box.
Notice that the Louw-Nida gloss is present on the right, but missing on the left.

If you want to replicate this yourself, note that Logos will apparently cache the results of the BWS run from the RI lookup. So to replicate this bug run the BWS from the guides menu first, then from the RI.
