I was doing the exact same thing. I was done with my FT8 and wanted to check things out for this weekend’s contest. I could see lots of RTTY on the P3. So I tuned some of the stations with MTTY and no decode. I did eventually find one station that was decoding. It was a W7 station.
That meant something was working. Then, I changed baud rate - set it to 75 and now I could decode most of the RTTY traffic I was seeing (some of the weak ones or the 45 stations - not so much). The source of most of the RTTY I was seeing at the time was the BARTG Sprint 75 contest.
Maybe you ran into the same issue.
