Is this norminal? I’ve always associated green flame with engine death, or ignitors. Didn’t appear to happen on 7-14.

Yeah, it is, it all depends on lighting, it's the excess engine igniter fluid (TEA-TEB) being expelled. Harder to see it during a day landing or if the ASDS has the surface lighting turned on. The fluid takes some time to burn off and if you see an F9 on its side in the integration building, you can usually see the three landing engines stained by it.
here is another example from Starlink Group 7-12.
