Block parameter settings from library blocks are not maintained in model

Hello,

I created my own library which contains an inport block from the Simulink Source Library.

I changed a few of the block parameters via Matlab commands and the settings seem to hold up within the library. But when the custom inport block is inserted into a model the parameters are changed back to default values.

Right now my solution is to change the parameters via an initialization function, but that is not very elegant. What am I missing, the library works fine apart from that.

(FYI: I am setting for example the 'Signal Logging' parameter of the inports outport to 'on'. )

In a hopeful way, best regards Miriam
