Edge 1040 Stamina not working after fitting a power meter.

I have been using my edge 1040 and the stamina prediction has been working well when I have just been wearing my hrm. I have now added a power meter and the stamina now shows <1% straight away?

Any ideas?

do I need to reset something?

You might need for the unit to build up some power data history first. It uses the power curve and FTP, VO2 Max and LTHR values.
