Strange discrepancy between single and multiple directoty compareisons

[wus]

When I compare a single directory (and its subdirectories) between one of my local drives and its counterpart on the NAS, the comparisons runs through without any error message.

However, if the same directory pairs are just 1 of several on the same drives, I get error messages for that very same directory pair.

When I click Wiederholen (retry) it proceeds to another subdirectory of ...\Heimat\ and finds a few more that it "doesn't like" but eventually it reproduces the first of the error messages that he screenshot shows.

Looks like a bug to me, but do let me know if I missed something here, and more importantly, how it can be avoided.

Thank you in advance for any help, hints etc.

- In the first screenshot you are comparing folders from drive F: to drive G:
- In the second you are comparing folders from drive F: to drive Z:

Which likely means Z: is a network location, and this is also likely a permissions issue
