KB4493446 Keeps Reinstalling

Hi,

I have several Windows 2012 R2 servers that keep trying to reinstall the same patch. KB4493446. 2019 - 04 Security Monthly Quality Rollup. (This is being install Via a Wsus server.)

The history actually shows that the patch install successfully, and there is no rollback. Yet every time I check for updates it keeps trying to reinstall. I have tried delete the SoftwareDistribution folder. 

I have download the Patch and tried a manual installation but it still tries to reinstall. It was stopping other patches from installing but after I installed all the other patches separably they installed. 

I assume that because its a security patch that it should be installed. 

I did read that there may be an old "Trigger" patch that need to be installed but I don't know what this patch is. See link

If anyone know a solution it would be great to hear it?
