If you need to fix this bug and you can not wait for an openplotter update, do this:
Code:
cd
mkdir delete
cd delete
git clone https://github.com/pypilot/pypilot
git clone https://github.com/pypilot/pypilot_data
cp -rv pypilot_data/* pypilot
cd pypilot
python setup.py build
sudo python setup.py install
cd
sudo rm -rf delete
