Why does my Phone app always prompt me to choose "Send using" when I've already selected "Always" for Messages?

Why does my Phone app always prompt me to choose "Send using" when I've already selected "Always" for Messages? 

After a call doesn't go through, a screen pops up with a choice to phone, message or video this contact. Whenever I click the Message button, WhatsApp and Messages pop up, even though I've already selected "Always" for Messages several times.

The odd thing is that Whatsapp isn't even a choice for the text messaging Default App in the settings.

I figured it out! It was YouMail. Any ideas how to prevent this app from doing this?

@AramH Deleting the app would work.

It will resurface. Its not a third part app issue. My device does it and i do not have youmail. Its done it since the last update within stock apps. From the code ive been sorting through, its the default app settings not setting the default apps properly. 🖖

It also did it with Truecaller so I believe it has something to do with "other apps" (whether third party or stock) overlaying on the phone functions

That makes sense. I dont have 3rd party apps but there is a new update today and i haven't had it pop up since the update.

That's what I ended up doing.
