Configurator not working for latest FMB910 firmware

Hello, i recently updated the firmware in my FMB910 devices through FOTA,
The firmware version is 03.27.13.Rev.03.

Unfortunately not even the latest available configurator gives the option of creating new configuration for this version. The latest visible option is 03.27.12++

And no matter what I do when I try to create a new configuration for FMB 910 a error window pops up and i get the error 'Invalid Configuration Error; Hardware MTB1:2 has already been defined, it can not inherit MTB1:1

Hi Ashamin,

Good day, probably this is a bug from the configurator, kindly try to download a different configurator

Please test this configurator:

Unfortunately i am facing the same problem with this configurator and the problem is only with FMB910 devices. I am able to create configurations for all other devices.

One thing that i have noticed is that when i search for FMB910 the picture of the associated hardware is different. It seems like a bug in the configurator that is being carry forwarded

will appreciate support on this issue
