Dataview plugin in v1.4.5, Task completion dates

Also bugs are for Obsidian, not for 3rd party plugins. For problems with plugins, you can try the troubleshooting steps at the troubleshooting guide, or you can raise an issue on the plugin’s Github page.

If you want help, please give more detailed explanations of what you are doing and where.

Which plugins are you talking about? I assume some task plugin that gives dates. And what does Dataview have to do with it?
