Unexpected behaviour with v16 loudness meters

Hi. I do not have a broadcast background, so I might be missing something here.

Project is set to target -18 LUFS
Sequence is edited, played back, and shows Integrated of -1.0
If I nest that sequence, reset, playback Integrated shows +5.5

The dbs registering in the M1 are the same.. as is the peak in the Control Room. Why would the LU differ?

Thanks in advance.

Ok, I have fixed this by cutting and pasting into a new sequence, and now the nested version behaves as I'd expect. The only thing I can think that might have caused it was that I started the project with a different target loudness level.. so perhaps the old timeline remembered the old value?

Not sure. Anyway, it's working now!
