SOLVED: Unwanted junction dots automatically inserted

Schematic
1

Hi,

I’m extending a schematic started with version v5.1.5 with the new v5.1.6, I added an extra hierarchical sheet, cleaned the old component names, renamed the whole schematic and ran ERC, now I have some unwanted junction dot in my new sheet (I deleted some already before noticing that something as going on):

I took a look at the other sheets in the schematic (the was that were already there) and all looked normal, however I am not sure when this unwanted junctions appered in the design (I suspect the reannotation or the ERC, however, I haven’t been able to reproduce it again).

Application: Eeschema
Version: (5.1.6)-1, release build
Libraries:
    wxWidgets 3.0.4
    libcurl/7.66.0 OpenSSL/1.1.1d (Schannel) zlib/1.2.11 brotli/1.0.7 libidn2/2.2.0 libpsl/0.21.0 (+libidn2/2.1.1) nghttp2/1.39.2
Platform: Windows 8 (build 9200), 64-bit edition, 64 bit, Little endian, wxMSW
Build Info:
    wxWidgets: 3.0.4 (wchar_t,wx containers,compatible with 2.8)
    Boost: 1.71.0
    OpenCASCADE Community Edition: 6.9.1
    Curl: 7.66.0
    Compiler: GCC 9.2.0 with C++ ABI 1013

Build settings:
    USE_WX_GRAPHICS_CONTEXT=OFF
    USE_WX_OVERLAY=OFF
    KICAD_SCRIPTING=ON
    KICAD_SCRIPTING_MODULES=ON
    KICAD_SCRIPTING_PYTHON3=OFF
    KICAD_SCRIPTING_WXPYTHON=ON

    BUILD_GITHUB_PLUGIN=ON
    KICAD_USE_OCE=ON
    KICAD_USE_OCC=OFF
    KICAD_SPICE=ON

p.s. also those red arrow seem out of place because those pins are not connected.

Somehow I had two symbols on top of each other. All is good now.

Some other notes:
Pullup resistors for a UART are “unusual”, especially for the output.
Does this uC not have internal pullups?

You’ve shorted your crystal to GND, some caps are missing there.

Thanks a lot Paul :slight_smile:
