Using BIAB 2025 (1124)

Working on a song with instruments and a single vocal track. Decided I wanted to make the instrument solo longer, so I have to slide the vocal over so it comes in at the right place. Trying to use the Audio Edit Window function. But when I copy one measure of silence (first photo) and then paste it in , the vocal shifts by two measures (2nd photo). Is this a bug or I’m doing something wrong?

Thanks,
