Problems with the Personal Dictionary (shortcuts) on One Plus Five

[thebaldfox]

Hey guys, not sure what's happened but i recently purchased a one plus 5 (2months ago) and everything was working flawlessly. I set up a personal dictionary, so if i wanted to say type "happy birthday" i would just type "hb." This was working perfectly until a couple of weeks ago. I can't say when it stopped, but now i can't get it working at all. I have russian, english keyboards. I had the personal shortcuts under english. This stopped working, so i moved them under the "general keyboard" that worked briefly and now that's stopped also. I did a quick search online, but didn't find much. Anyone else have this issue ? Can they shed light on it ? Am not running the latest Oxygen OS as it's not reached me yet. App wise, i had the standard keyboard. thx
