'Format Error' when trying to set V1/VR/V2 speeds in MCDU

I’m currently doing quite a bit of flying in the FlyByWire A32NX. Every time I program the MCDU though (after importing flight plan from SimBrief), when I try to set the V1/VR/V2 speeds in the Perf screen, it says ‘Format error’.

I think this is more likely user error on my part, rather than an issue with the FBW A32NX. Not sure what I’m missing though. Before trying to set the V1/VR/V2 speeds, I’m setting flaps 1 in the same Perf screen.

thanks

Never mind. I figured out how to calculate V1/VR/V2 speeds in SimBrief (in Performance & Tools), then manually plug these values into the MCDU instead. In some of the MCDU tutorials I’ve watched, you can just click on V1/R/2 buttons and it automatically pulls these values from SimBrief, but manually entering them only takes 30 seconds, so no big deal.
