Restore error - Failed to patch with remote file

Since my last post, backups seem to have being going fine. Today I tried using the GUI under the job to restore a file (an MS Access database, *.accdb) to replace my version which seemed to have a problem. The file size is approx 6MB. Apart from using an awful lot of bandwidth it appeared to be working fine. It spent quite a few minutes saying “Downloading files”, considering that the B2 bucket has only 37 files with a total of 147MB and surely it doesn’t need them all!
The first attempt threw an error, I think it seemed to indicate a problem with the location. Log info is below (I trust I’ve pasted the right log):

* Mar 14, 2019 2:40 PM: 1 remote files are required to restore 

So I tried it again restoring the file to my Desktop folder. But the resulting file was smaller than expected and worked no better than the current faulty version. The next attempt did not even have a resulting file to show for it.
Here is another saved log FWIW:
