DRC Error in KiCad

Hi all! I hope this is the correct place to post my issue... I've got an issue with KiCad DRC, as illustrated below... (see DRC.png)

First error pointed by the design rule checker is that pin 1 of connector JP4 is not connected... although it is logically connected to the capacitor C2 on RST on ATMega328. (see error1.png)

I've tried several workarounds:

1. direct connection,
2. separated wires which same label effectively attached to both wires (one on connector, the other one on capacitor)
3. label attached to pins directly (one on pin1 of JP4, the other on capacitor pin), without wire

No way to solve the problem, I get the same error message

Second error is one of the same kind on pin 1 of the battery management chip ( MCP73831). (see error2.png)

I now plan to edit the netlist manually to create this connection.. Is this a acceptable workaround??

Another strange point - but this one has been solved - is that although the GND pins are defined as power input in the symbol library, I need to add a label GND to the attached wire in order to get rid of a message error type 2 ( pin not connected...)

Has anyone encountered this kind of problems? Thank you Greta @FablabULB
