I have discovered two problems with Terminal Generator v2.1.4 (Custom Tkinter), the first is also present in version 1.
I use "Linux Mint Debian Edition" with Linux kernel "6.12.85+deb13-amd64" and "Cinnamon 6.6.7".

1 - The plugin does not consider the setting  Settings -> "Configure QElectroTech" -> Project -> "Number the title block column from 0 (1 otherwise)"
     When the setting is checked, all the references generated by the pluging are displaced by +1 .
     If for example a terminal is placed in 1-D4 it will be shown in the generated block as 1-D5

2 - The second problem is related to the Settings page of the plug-in. When I click the button Settings I get an empty window.

Thank you very much to all the QElectrTech team and contributors, and thank in advance if somebody can help me on those issues :-)
