I am trying to insert a FC i have made into a FB block, the FC is very simple, 2 byte inputs and 4 bool outputs, some simple SCL code and no dependecies. when i try to import the FB it gives me the error
"An instruction with the name 'Safety_HMI_Status' cannot be found at the object with UID '21'."

my code works if i change the name Safety_HMI_Status, to a standard block taken from the tia project, and it works with no other blocks i have in my project which isnt a standard block, so i dont know if it is some read permissions i dont have properly done or if this needs to be in some specific place for the openness to be able to read it, i have tried placing it into the folder "system blocks > program recources" but this didnt help.

i linked the xml, the error comes from line 590

any ideas on what to try?
