Unable to zoom out historical data on the mothly TF.

Dear Ctrader. 

I come across lately with an issue it never happened to me before. 

I can zoom out with any TF except with the monthly. 

Example:

- This is the weekly TF an as you can see I can zoom out as much as 27th of august 2000 where historical data started on AUDNZD in particular,

However, if I use the monthly TF I can only go as far as the following date.

Price only is shown till 31st of October 2016 missing the data left until 2000.

I'd like to get it fixed, please. 

Thanks in advance.

Daniel
