Is anyone else having problems with extending staking ??

I kinda feel like I am missing out on extra rewards due to this issue which I had brought up about 6 weeks about or at the start of the new quarter. 

I realise its gonna be at least 2 years before we are in FULL BULL MODE so wanted to extend my staking for another 4 quarters to gain the most rewards over the next few years but each time I click on EXTEND it automatically reverts back to 1 quarter and opens my metamask to confirm. 

Is anyone else having issues with this or is it just me ?

Thanks
