When I bought my already-flying RV-7, I noticed the same thing on my Skyview system. System was keeping the battery charged, but showed a discharge when the engine ran but positive current when the it wasn't...
I found the amp shunt under the panel and reversed the two small "sense" wires located on it. Apparently, the original builder just had them reversed.
That made the indications normalize and all good now in the ~400 hours since...
Obvious question...is it showing a discharge but is the system keeping the battery charged?
If so, perhaps go looking for the shunt...
