In what way is it not working, does it exclude traffic you want or include traffic you didn't want?

Do you have VLAN tagged traffic?

The capture filter is not used when two interfaces are defined. I tried it and I've the same issue. Bug?

It depends on where you put the capture filter in the argument list. See the man page entry for the -f option:

This option can occur multiple times. If used before the first occurrence of the -i option, it sets the default capture filter expression. If used after an -i option, it sets the capture filter expression for the interface specified by the last -i option occurring before this option. If the capture filter expression is not set specifically, the default capture filter expression is used if provided.

The behaviour can be verified by omitting the -k flag and opening the Capture Options dialog and inspecting the capture filter for each interface.
