File Manager ot showing Directories named as numerics

[yourPAGES]

We're running 7.5.3 and have a directory that contains other directories all named as numerics-only (0, 1, 2 etc.), but Plesk File Manager refuses to display them even though its counter shows that it knows they're there. This only seems to occur when the number of directories exceeds more than a single page.

Additionally, if you then use Search to look for let's say "9", then it does manage to show *some*, but not all, of the directories.

screen-paste showing counter of 119 directories, but no display...

1-1 [domain] / httpsdocs / files items of 119 total Pages: First << 1 2 >> last Number of entries per page: 10 25 100

screen-paste showing search for "1" which does display some of the directories...

Any ideas why we're seeing this behaviour?

Thanks,
