[SOLVED] Redline under parts

[J.Tax]

Hello everybody,

I'm having problems with Altium. When I have imported my schematic, some custom parts/resistors and LEDs wont shown connected in the PCB. I'm troubleshoothing for 1 hour now and saw that there is a red line (see picture called: 'red lines') underneath my MHDR's, where my parts a connected with, and my suspection is that it wont connect because of this.

Does anybody know what this means?

Duplicate component designator ?

Tools -> reset duplicate component designators.
after that
Tools -> annotate schematics quietly

If this does not fix it , please attach or upload the files i can have a look at it.

Thank you very much, this was indeed a problem for the generation of the PCB.
