Sync a page display with an attachment display results

Hello,

I am doing a view with two displays, one is a page and the other one is an attachment block (it's a map view) and I would like that both displays would show the same results.

At this moment this only happens in first page: both displays show results 1 to 10, but when page #2 is loaded the page display shows results 11-21 while attachment block displays 1-10 (the same results than before).

Is there any way to solve this issue so both displays are synced?

Thanks
