Schematic connections not working with labels

Hey,
today I am coming up with a weird problem. Its is best declared with images:

The Warning in ERC: Warning: TEST_LABEL and INPUT_1 are each connected to the same part. TEST_LABEL is used in the netlist.

I do not know what to do. I really need the label there because I have very many of these inputs and want to create a clear and well structured schematic. Any help appreciated. Best regards.

This is just a warning and you have to decide for yourself if this is good in your case.

If you put a label onto a wire the wire gets the name from the label.
Obviously if you put 2 (or even more) labels onto a wire kicad has to decide which labelname it takes for the wire.
This is the case in your second picture. In the bottom left you have put two labels (“TEST_LABEL” + “INPUT_1”) onto the wire. Now Kicad decides to take the name “TEST_LABEL” as official name for this wire. Due to the connection on this wire all other wires with labels “TEST_LABEL” and/or “INPUT_1” are also connected on the schematic. If this is what you want - all is fine.

To get a overview of all connected nets try to highlight (see hotkey section for this command) the wire - then all other connected wires are also highlighted.
