Is there a limit on future planning in rotas?

I’ve been updating the rotas for my church but it won’t let me go further than the first Sunday in March (i.e. 8 weeks from now). The Rota is linked with the recurring calendar event which goes beyond that, so I’m just wondering whether it is restricted (anticipating that no one would be organised enough to plan more than 2 months worth of service rotas!).

Many thanks,
Mark
