18.104.22.168 is the version of the extension
8.8.0 849 is the latest version of VSE
Have you checked in the VSE Product package as well as the extension?
Menu -> Software -> Master Repository
At the bottom of the screen is a "check in package" button. Click it and load VSE880LMLRP1.zip and it should then appear in the list of the deployment task.
Apologies if you've already done that. I'm answering via the power of Google translations
