Problem with Legrand 067775/741811

[EXP-Carthage]

I notice a "bug" concerning the update of Legrand devices 067775/741811.
Indeed, I have devices in version 0016 and the available update is in version 004a.

When I consult the database.db file, the swBuildId section gives some strange information:

"swBuildId":"016\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000 \u0002\u0000\u0001\u0000 \u0002\u0000\u0002\u0000!\u0012\u0000\u0000\u0000\u0000��\u0003\u0000\u0010\u0002\u0001\u0004\u0000\u0018\u0002\u0000��!"

So it is impossible to update and I get this error:
Firmware on '0x00047400000a79ae' is newer than latest firmware online.

Is it possible to correct this problem? See maybe a method to force the installation of the update?
