Log shipping monitor primary not seeing recent backups, warnings triggered in error
You are correct the last backup time is showing 2017-02-09 12:15:02.010 while last copied and restored are much greater 2017-02-09 16:32:02.397 and 2017-02-09 16:34:11.477. So I believe somehow the catalog is not getting updated. There can be two reasons:


This can be a bug make sure  SQL Server 2008 R2 is patched to SP3
There was old logshipping which was configured and was not removed correctly and completely.


I believe the solution here would be to drop and recreate log shipping.
