I can't say I've had this issue, so not sure what to suggest, but if it was me, I'd back up my texts using an app like SMS Backup and Restore (I use this weekly and upload to google drive), then you should be able to delete them all from your phone, and restore them from the backup. May be worth a try before just deleting them all?
Are you using just the stock messaging app from your phone? Maybe try a different one too, I use ChompSMS
