Hello and welcome to the forum.
I've ran into something similar on a couple installations, but....
I never let it bother me too much.
The System Reserved Partition contains a couple important files which your system uses at bootup.
The Boot Manager and the Boot Configuration Data (BCD) and that's all, unless you are using Bit Locker in which case it also holds some of the encryption data that your system needs.

SO... unless you are noticing some overall performance issues and your computer seems to operating normally, I would say that it is safe to ignore any issues you might be having with that particular partition with respect to the native Defrag Utility (Defragment and Optimize Drives).
