Managing maps on 700 and SD card

I bought the CityNavMap 2 days ago and downloaded into the SD card and I cannot see it in GarminExpress when I clicked on ManageMaps.

So, I downloaded it again but this time to the 700. And, I still cannot see the new map under ManageMaps. And, yes, I have shutdown GarminExpress and relauched it. It cannot see it.

But, when I launched BaseCamp, it can see the new map BOTH on the device and on the SD card.

What's going on? Can you help me to troubleshoot this, please?

I do not want to keep both copies.
