Search function does not work anymore in ver. 5.1.3 - bug?

The 'Find files' function that worked perfectly in 5.1.2 doesn't seem to work anymore in 5.1.4
If I go to 'Commands' -> 'Find Files' and enter any search term (like mysearchstring, mysearchstring*, mysearchstring*.*, etc), I get a lot of irrelevant results that don't mach the searched string in any way.
Can you please confirm? Is this a bug?

Additional information:
- using SFTP
- connecting to a UNIX Server
- using default values for all additional settings

Regards,
M.R.

I am searching in the root.

Thank you,
M. R.
