Latest Event Module Not Linking To Events

I am using the current version of JEvents Core. The JEvents Latest Event Module no longer links to a calendar event if more than one category is selected in the Select Categories field. If only one category, or no categories, is selected, it works fine. When two categories are selected, I receive the following error message:

Forbidden

You don't have permission to access /calendar/icalrepeat.detail/2018/11/06/13873/200|201/announcements on this server.

When the event is selected from the calendar with the following URL is works:

/calendar/icalrepeat.detail/2018/11/06/13880/-/announcements

When only one category is selected, the following URL works:

/calendar/icalrepeat.detail/2018/11/08/13880/200/welcome-back-dinner

However, when more than one category is selected, the following URLfails:

/calendar/icalrepeat.detail/2018/11/08/13880/200|199/welcome-back-dinner on this server.

Note there are two category IDs in the URL ("/200|199/" (. When only one category ID, or a "-" is in the URL (like the ones above), it works.

Thanks for your help,

Jim
