ADALM-Pluto Simulink Transmit Block error launching filter wizard

Hello

When trying to use the ADALM-Pluto transmitter block in Simulink I get:

When I hit the "Launch filter wizard" button I get "Not enough input arguments". I get this no matter what the configuration I set to the rest of the block (I've tried a lot) so I don't know what "input arguments" it is talking about. The picture above only shows the transmit block by itself but I've had it set up with external components as well. BTW, the Pluto does work and is able to transmit so that isn't an issue. I just can't get the filter wizard to come up.

I should note that I tried the same thing with the receiver block and got the same error.

Anyone else seen this issue?

Thanks
