Outdoor ride; power drops

Just wondered if I’d missed a setting & if anyone can point me in correct direction.

I use an Ant+ to BT bridge outside TR for HR/Power etc. Occasionally it fails to output a power and it drops to 0, although the cadence shows I haven’t stopped. Is there a way to get it to ignore the drops or interpolate between them if cadence continues? I used to use Training Peaks and I’m pretty sure it corrected for them.
