Multiplicity of Required Interface

[Eyk]

Hello,

I use EA 9.0. I have a question:
I want to create a component diagram. In this diagram I need to add a required interface with a certain multiplicity to a component. I can select the multiplicity of the required interface using the "advanced" context menu, but the chosen multiplicity is not shown in the diagram.

What am I doing wrong?

Thanks in advance!
