issues with tap and flow interchangability

I have the latest version (7.3.3.12) of Swiftkey on my Samsung S9+. For awhile now I've had an issue with the keyboard. I do a combination tap and flow on my phone keyboard, but when I do this the keyboard layout changes from the letter keyboard to the number keyboard and interrupts my typing. It's super annoying. I've uninstalled and reinstalled the app and it's still doing the same thing.

 

Anyone have this issue? Any suggestions to correct this is appreciated. I eagerly await your reply.

 

Thank you
