Two of my contacts are internally being mixed up Recently I've stumbled upon a very weird and cumbersome bug. Android mistakes one of my contacts for another. As far as I know it happens to exactly one pair of contacts on my phone (let's call them A and B). When trying to message A, it shows the proper message history, but the messages are sent to B >&lt; This causes a lot of confusion for the recipients, and for me as well. 

I've tried using a different messaging app (instead of the default one), but the end result is just the same.

Here's the bug captured on video:

And in screenshot form:


I enter the name of contact A (starting with "Lucyna")





I select the proper suggestion and I can see the message history with A:





I tap the message field, and the moment it gains focus the name of the contact in the top bar changes to contact B!




Sending the message now causes it to go to the wrong person.

The two contacts aren't related in any way, and I have no idea why did those two in particular get mixed.

I'm on Android 7.1.2
Removing BOTH contacts and recreating them resolved the issue.
