You could try the following alternate workflow:
- Insert the leveler plugin in the Master Section
- Use the settings like on the picture
- Click on the button “Render In Place” (or simply use the shortcut).
In the Render option, there is also a crossfade option that you might find useful.
This workflow is quick: select audio, render with the shortcut, select audio, render with the shortcut, etc.
Internally, the mechanism is very different than the one with the render dialog. Maybe that will allow you to avoid the problem. If you try this, your feedback is welcome.
