Vodafone account update SMSs being stored under a contact's messages

[cja123]

I'm using a Huawei P9 Lite, and all my SMS from vodafone (statements, promotions etc) have been saved in with the messages from one of my contacts. I have no idea why this is happening. See the screenshot attached - I haven't included any personal messages from my contact in there, but they are there.

It's possible this is a resource issue.   Try clearing recent apps, then the system cache (go into Settings|Storage|Phone Storage then Clear Cache).   Finally, restart the device.   If that doesn't fix it and your storage is nearly full, consider removing any content and apps you don't need now, or moving photos, music etc to an sd card - if you haven't already).
