I've recently started using JEvents on a Classic Car Club website, all work great except.....

We have 2 regular events that occur on the first Thursday and the third Wednesday of every month, if you view by month then they are there and can be seen well into the future as expected, but if you switch to Year view then they are only there for the following month (currently March), but nothing after that.....am I missing something that would cause this issue?

Website address: https://www.tssc-devon.org.uk/events

Any help would be appreciated.
