Transfer speed in transfer queue shows KB/s, MB/s, GB/s (etc.) ONLY, regardless of the preferences

[Wuzzy]

In FileZilla, it is possible to select in the preferences how file sizes are shown. If I select for example the IEC style (KiB = Kibibyte = 1024 Byte) instead the default "Byte" option (=no KB,MB,GB,etc. just Bytes), FileZilla applies this perfectly to everywhere where file size appear, EXCEPT when one file gets transferred. Then, in the transfer queue, the transfer speed of all is still shown in the "KB/s" (for example) format instead of the "KiB/s" format which I selected in the options. All other file size numbers are formatted as selected in the settings. It seems the shown transfer speed completely ignores my settings; it also shows "KB/s" if I selected to show only Bytes.
