Issue using Cryptomator and Directory Opus

With the closing of Boxcryptor, I have moved to Cryptomator but have found an issue when searching for folders using Directory Opus.
Directory Opus appears not to search inside sub-directories of encrypted drives.
I use a hierarchy of subfolders within the encrypted drive, but Directory Opus reports no matching folders when I ask it to search for a particular part of a directory name.
When I use Windows Explorer to do the exact same search, it finds them.
Is there a solution for this issue?

The issue is in their side. See Problems with searching files in a Cryptomator vault
