When creating a publish from the Publish Templates screen's search container menu and clicking on Cancel, processes screen is displayed instead of the Publish Templates screen.
Same issue with export templates.
- go to Publishing -> Export
- choose Export Templates from the upper kebab menu
- add a new export template (if there is not any existing templates)
- choose a template and click on Export in its kebab menu
- Click on Cancel
processes screen opens
export templates list screen should appear
