This worked for me (I'm going to type exactly what i did and this is easiest method i could explain -don't ask why :| ):
1. Click on "Text Entry Settings..." under EN language icon (or whatever else if it's not your chosen language)
2. in 'Switch to next source using' >> PRESS "Shift R" then PRESS "Alt + Shift R" >> text inside this section should be "Shift+Level3 Shift" !
3. in 'Switch to previous source using' >> PRESS "Alt + Shift R" >> text inside this section should be "Alt + Shift R".
This is weird but worked for me. I tried it on Ubuntu 16.04 LTS.
