In the SBL Greek New Testament, if I long press on a word, the pop-up information lists the correct word in the title of the window. But the word shown for "text", lemma, meaning and Bible word study are for a different word. The "Search SBLGNT" option lists the correct word, however. It appears to list the previous word, rather than the selected word.
Also the Greek of accented letters often shows a boxe instead of the proper Greek letter.
