Bug selecting list options

Selecting 'Commands > Connection > List Options > Show Hidden Files [-a]' results in the Resolve Links [-L] option being selected or deselected instead. And looking at the server commands, it doesn't look as if the -L option is being sent at all (following example is with -a -l -L options all selected):

PORT 10,3,3,5,4,51
200 PORT command successful
LIST -la
150 Connecting to port 1075
249 bytes transferred. (24.3 KB/s) (10 ms)

Smart FTP version is 1.5.990.2 and I've tried it on 2 PC's.

Not reproducable.
