I'm trying to switch a few updates from "metadata only" to "full content" after they've already been published. Apologies in advance, I'm sure I've seen this posted somewhere but for the life of me cannot find any information on it

I appreciate I could wait for the next release of the update(s) but who knows when that could be. I've tried the following method and had mixed results:
- deleted the update using the Modify Published Updates Wizard (Advanced tab)
- run a full SCCM Software Updates sync, once complete, confirm update(s) expired
- start a sync from PatchMyPC Publisher # this will trigger sccm software updates sync
- once complete, confirm update(s) published with full content
I'm obviously missing something as the updates return as metadata only
