Visual studio 2017 Info.plist lose Distribution Destination after tab change

I've a problem when release IOS app with Visual Studio 2017 that i can reproduce doing the following opertions:

1) I need to change the IOS destination version to 9.0 because i must support olders device, so i edit the Info.plist like below:

2) I publish my ipa file as usual and my destination version of the builded ipa is 11 (i can see it uploading on diawi but even trying to install on a ios8 device that show me the error "Unable to download {app-name} at this time")... mh nice... i go back to Info.plist and i see that the Destination version is blank:

3) I try to edit it again but when i change "tab" or build .ipa file I come back to point 2.

I've just tried the standard things like delete bin/obj and rebuild or disconnect-reconnect the mac but nothing works :(

Some useful things:

1. On IOS 11 the ipa file works perfectly.
2. I'm using an Enterprise realease Certificate.
3. My Mac XCode Version is 9.2 (I've not enought free disk space to upgrade. Updated but no success.
