EVAL-ADPDUCZ Cannot upgrade the Firmware ( possibly due to driver mis identification)

I have recently purchased the EVAL-ADPDUCZ. However as soon as I attempt to use it it requires a firmware upgrade. Each time I try this is says 'Could not connect to device' device is not in boot mode. We are running Windows 10 fully updated and have tried on three different machines.

However, the device is in boot mode. We know this as we cannot then connect in the normal manner and we get a software driver pop up in device manager telling us that the device is in boot mode.

We think that it may have something to do with the fact that the STM32 Bootloader driver is identifying itself differently to the one shown in the manual as shown below. It is called STM32 BOOTLOADER as opposed to the manual which says it should read 'STM In Device Firmware Upgrade'.

Does anyone have the same issue or know of a fix. At them moment the kit is totally useless. 

Many Thanks,
