Aeotec Siren 6 and Doorbell 6 firmware different and not behaving the same

I have a Aeotec Doorbell 6 and 2 Siren 6 - all are using the Aeotec Siren 6 New driver. The Doorbell works as expected - tell it to play a certain tone, and it does. The Sirens, however, do not work that way - tell then to play a certain tone (Events show correct tone), but what is played is the "default" siren tone.
I notice the State Variables are radically different between the Doorbell and the siren:

The firmware reported on the Doorbell is 1.5, but on the Siren is 1.05 - Aeotec support page does not list any available firmware updates, so I don't know if I have "old" Sirens, or if the firmware reporting is wrong.

New to all of this (hey there!), so there may be some "trick" I am unaware of. Any insights appreciated. Amazed at the quality of information and community on this forum, BTW.

Well, had a nice email exchange with Aeotec, and they confirmed that the firmware IS the same. Seems the issue is with the Aeotec Siren 6 New driver - no Component Chime is created with this driver, either.

Here is what Aeotec said about the firmware:

V1.5 and V1.05 are the same, its just listed differently.

V1.5 (or V1.05) with the decimal point is stating:

Version 1
Subversion 5 / 05 (while it isn't 50, if it was 50, then it would state V1.50 instead)

​V1.5 is not the same as V1.50, but it is equal to V1.05. (its just that the value 0 in front is dropped).

Did you hit "Configure" after saving the drivers?
If I remember correctly I had to do this for my Doorbell 6 to make it work.

Mashed that Configure button I don’t know how many times. Totally unsatisfactory user experience when you do that - it just sits there, looking gray, taunting you with its ineffectiveness.
Configure worked when I switched drivers on my doorbell, too - but no joy on the Siren.
