FR955 vs. EDGE830 training status?

Question

Hi everyone, 
 I searched many resources but still no success on this one. 
 I'm on my new FR955 Solar for 1 month now, replacing a previous broken FR955 Solar. I also have an EDGE 830, which is my only training device. 
 
 Since I got my new FR955, Training Status on the Connect App shows 3 different values: one for the new FR955, one for the old FR955 and on for the 830 (which is quite annoying... then I discovered they are apparently looking at different time intervals backwards so they evaluate Training Status differently...?). 
 Connect used to show the 830 status only, but now it has changed and I cannot find a way to disable Training Status (or hide?) for the new and the old FR955 (moreover, it shows the new FR955 value in the main page, as it is the "Primary waerable", and the EDGE 830 cannot be set as primary device). 
 I'd like to do it because the 830 is my only training device. 
 Looking for hints... 
 
 Thanks!

Delete the old 955 from your Garmin devices. The associated data doesn't get deleted from Garmin Connect. 
 Per Garmin: " The Device Compatible with Unified Training Status with act as the PTD by default. The device without Unified Training Status will still generate its own Training Status that will be visible on the device itself, but the Training Status on the PTD and in Garmin Connect will be the true Training Status. You will no longer see the option to toggle between different device's Training Status in Garmin Connect if a PTD is set on the account. "
