There are several instances in the Lexham LXX materials where appearance is misspelled as appearence. This is in both the Analytical Lexicon and the LXX interlinear translation. The former I can submit a report typo for but I can't seem to be able to do that for the interlinear text. It looks like the same is true for the Logos LXX so you need to make some systemic corrections. I see that the hover for Swete's LXX is showing Strong's 7200: "appearence, vision, appearance." Perhaps these are all tied together somehow.
