Found the solution,

the NO-element had the wrong property "switch state".
It was: "Switch normally closed", but must be "Switch normally open".
Saved the element in the user library. Done for now.

Maybe the development/main branch should be fixed?

On what branch is the nightly development build based? 0.100.0 DEV 8445 ?

I'm using element (Magneto Thermal Circuit Breaker):

project0+embed://import/10_electric/10_allpole/200_fuses_protective_gears/12_magneto_thermal_circuit_breakers/disjoncteur_magneto-thermique.elmt

and the NO-contact:

project0+embed://import/10_electric/10_allpole/310_relays_contactors_contacts/03_contacts/contact_gv_no.elmt

and the NC-contect:

project0+embed://import/10_electric/10_allpole/310_relays_contactors_contacts/03_contacts/contact_gv_nf.elmt

And linked the two slave components to the master.
But the slave components show up at the wrong column in the master component:
I expected the NO-contact (4-B5) to be in the left column, but it ended up in the same column as the NC-contact.

I'd like to have the project title in my folio name.

Example:
Project title: RK_01

Folio numbering:
Text: =%projecttitle+
Text: A/
number format 1: 0

Output result of the folio name: =%projecttitle+A/1
Expected output for the folio name: =RK_01+A/1

I tried to use the %projecttitle and %{projecttitle} but neither works.
I guess the variable %projecttitle is not available in the folio autonumbering... am I correct?
I think it would be nice to have it available.
