Expiration date setting not copied with backup

[yehoshua-og]

Hi there, thanks again for this crucial plugin.
We are experiencing a minor issue where the expiration date setting returns to default (no expiration date) when importing the activity from a backed-up course (also when importing directly from a course).

We are using version 3.11.11 of the plugin on our 3.11.12 platform, I couldn't find release notes that mention this issue.

Is there a way to fix it?
That will help us a lot since this course is repeated more than 50 times yearly.

Many thanks!
