Keyboard: Spelling correction text-box appears but text is blank


Hi everyone.
When entering a text, the app correctly identifies when a word is spelt incorrectly, however it is blank where it usually provides the text correct spelling. See screenshot. Test device: iPhone 5S iOS 10.2

I noticed, it happen when in Settings > Keyboard switch off the Predictive.

But on the same device when I open, for example, Facebook app (native app) it works correct with the same settings. See screenshot.

Maybe somebody knows how I can fix it in my hybrid app (Ionic 2)?
