Messed up elevation data after wireless transfer from Ride With Gps

Hello,

Since a few weeks now I'm not able to get correct data via wireless transfer from RWGPS. 

When I pin or unpin a ride I get enormous spikes in elevation when loading the course up. See image attached. 
When I transfer the GPX file manually from rwgps everyting works fine. When I send the same course from garmin connect to the device, all works well. 

I already:

* Wiped my edge and a fresh install

*Transfer wifi and bluetooth (no difference)

* Loaded different maps (osm garmin maps etc...)

Any suggestions please.
