Problem with iPhone Text Replacement on Facebook

I hope I'm not the only person that's been having this annoying problem for months, but I bet I am since if others were too, I'm sure Apple would have fixed it already. I keep hoping & waiting but I'm tired of waiting.

I am a Facebookaholic AND I also have a bunch of Text Replacements setup.

My problem is, the Text Replacement feature is constantly, maybe always, automatically adding in the entire Text Replacement after I've only tap typed in the very first letter or 2 of any of my Shortcuts, not the whole thing.

As an example, say I have the Shortcut wh that should offer White House at the top of the keyboard that hitting the Spacebar will enter.

Problem is, that works here but on the Facebook APP, as soon as I type in wh, say to type "what", it fills in "White House" and the rest of the letters that I type in, it adds after that.

What's going on? Am I messed up? 🤔🙄
