DSEV mod engines creating 0g indication

[Cavscout74]

I encountered something strange - initially on a long range crew cycler powered by @Angel-125 DSEV "supernova" drive, the nav ball g-meter, mechjeb & a stock seismometer all read 0 g all the time - even sitting on Kerbin's surface.   This appears to be an indication issue, as the ship still accelerates normally.  I wasn't sure what part was causing the problem, so I took apart the entire ship one piece at a time and removing the fusion drive fixed the 0 g indication.   So I tried multiple engines, and I think every DSEV engine is causing the problem - Viper nuclear aerospike, supernova fusion drive & hypernova fusion torch.  Is anybody else seeing this or have an idea on how to fix it?  It doesn't affect actual gameplay, just appears to be an annoying little indication bug.
