AMS forgets K values after power reset

Hi,
I have a X1C since over a year with 2 AMS units. One was bundled with the printer and one I bought a few month later. It seems like both AMS are the same version/revision.

I mostly remove the power after I finished printing so the printer is not running idle over days, so my printer is booting frequently.
After every reboot I have to manually select the K values again because all slots have empty k values. I can do this directly on the printer over the display or in the bambu studio, after another power cycle the values are gone every time.

I thought this was a limitation of the AMS and also have seen other people complaining about that on reddit etc…
Now a friend has bought a P1S Combo recently and the K values are persistent after a power reset.

So it seems like the AMS/printer can save the values now? Is this a setting somewhere I cannot find or is there a new revision of the AMS which can persistent save the values now?

Are there any others with a X1C Combo >1 year where the K value is persistent after a power reset? Is it me or is it the product. :slight_smile:

Thanks for help

Anyone?
Tried to open a support ticket with kind of the same text but got only a copy paste answer.

Took a while but got a respond from the support.
The non persistent k value is only an issue on X1 series not the P series.
They are still working on it to get it also persistent on the X1.
