Energy tracking - Unable to add a new contract

[Nagromdark]

Hello,

I’m having a problem with the « Energy Tracking » integration.

I realized that I hadn’t updated the Tempo contracts for a long time, in fact, they have expired:

I therefore want to add the Tempo contract for the period from 01/02/26 to 31/01/26, I select this one:

then:

then preview:

then save and I get this error:

Is it something I did wrong or is this a real bug?

Thanks in advance
