Hi,

I've found a workaround for this issue. It looks like it's a bug. Details as follow.

Issue/Symptom: When using CalDAV to sync with Google calendars, non-repeating entries that are about 2 months into the future do not appear.

Workaround: It looks like there is an issue with the native Personal calendar. To make all entries in your calendars to appear, do the following (all from within Calendar):
1) Open up Calendar.
2) Go to Options > Manage calendars.
3) Ensure 'Show this calendar and reminders' option is selected for the calendars you want displayed including Personal (even if it's empty). At this stage, the bug is still active.
4) Tap Personal calendar and tap Save. Next, open EACH of the enabled CalDAV calendars and click CANCEL. Do NOT view your calendar until you have done this for all the enabled calendars.
5) Once this is complete, then it is safe to view your calendar.

Note that it is crucial at Step 4 that you do not view the calendar until you:
1) Tap Save for Personal calendar.
2) Tap Cancel for all the other calendars.
If you do, you will need to start Step 4 all over again.

Note when the bug reoccurs, just perform Step 4 again.

Hope that helps everyone. Feel free to improve the above steps if needed.

Cheers,
