Rubymine 2016.3.2: ruby sdk differs from system (rvm's) default when opening a ruby project for the first time

Hi.

I've created a new rails app:

%ruby -v
ruby 2.3.0p0 (2015-12-25 revision 53290) [i686-linux]
%rvm list

rvm rubies

ruby-2.1.5 [ i686 ]
ruby-2.1.9 [ i686 ]
ruby-2.2.1 [ i686 ]
=* ruby-2.3.0 [ i686 ]

# => - current
# =* - current && default
# * - default

%ruby -v
ruby 2.3.0p0 (2015-12-25 revision 53290) [i686-linux]
%rails new xyz

I then opened the project in rubymine. When I goto settings (ctrl+alt+s) / Ruby SDKs & Gems, the selected ruby version is different than the default (stated above as 2.3.0).

Oddly, if I open a terminal inside rubymine and type 'ruby -v' it gives 2.3.0 as the current version.

If I change the SDK to 2.3.0 and restart rubymine, this setting is persisted. However, I don't understand why rubymine falls back to 2.2.1 when opening projects for the first time.

Could you please assist?

Thanks!
