Tonight I accidentally came across information in chkdsk that explains the problems that are in the EFI partition.
When chkdsk has problems with fixing / recovering files it creates the chk files.
Macrium was not able to make a backup image when it reported an error.
The error was a cluster run error.
This required the use of diskpart, the labeling of a hidden partition and then running chkdsk /r on the partition.
This was the EFI partition.
This had been run many months ago and I did not know what to do when it prompted for Y or N and had chosen Y.
The log file below also displayed the system reserved partition had been on the storage drive.

C:\Windows\system32>chkdsk /r B:
The type of the file system is FAT32.
Chkdsk cannot run because the volume is in use by another
process. Chkdsk may run if this volume is dismounted first.
ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE INVALID.
Would you like to force a dismount on this volume? (Y/N) y
Volume dismounted. All opened handles to this volume are now invalid.
Volume Serial Number is 5C23-338D
Windows is verifying files and folders...

4,811,776 bytes available on disk.
1,024 bytes in each allocation unit.
97,280 total allocation units on disk.
4,699 allocation units available on disk.
The above is the log file that matches the date of the chk files in the EFI partition in the image.
So those are boot files?
Can they be deleted?
That may free up the space needed to perform Windows upgrade to 1803 and not get the "We couldn't upgrade the system reserved partition"
