Windows 10: System Restore points all disappeared except one system- created point

Hello:

I generally create a system restore point manually-daily. I dont rely on windows to create it for me.
I allow lots of space (~30%) of drive for SR. I recently decreased it to 20% when i noticed way more RP's than I needed.

Yesterday, I noticed all of the Restore Points-but one- were gone. There was only a System created point. SR was nowhere near the limit for FIFO to kick in! This had happened before. And when it did, I was able to continue creating points at will with no further issues. I had paused WU for a week--prior to all this..So there was no WU to generate such a System point

However I noticed that the system-created point was unusually small in size. ~300 MB. Generally my SR points are closer to ~1 Gig each. I tried creating a few more manual RP's. Yet with 5 restore points the total size is still only ~700MB. So I'm concerned if these are truly functional RP's? I'm not sure how to diagnose this

I can think of several approaches here:

1) Attempt an actua system restore to the most recent point and see if its really working as should. And if so, all is well..But this might be a bit draconian..

2) Delete all but most recent RP's and see if "flushing the system" that way resolves this

3) Attempt to diagnose if there are any issues in the Volume Shadow service via EventViewer.

I had forgotten exactly how to find System restore issues in EventViewer. Where exactly do I navigate to to find those events?
======================
Any suggestions as to how best to proceed to ascertain whether those points and future points are functional given that they are much smaller in size than I'm used to?

Thanks:

Windows 10 1903
