Fta channel don't open

I have installed last version of open atv 6.3 date 22/02.

Happen this.... when i start dm 900 the last channel FTA i have viewed dont open i can see the open atv logo so go to select another fta channel start this channel so i can open again to view. Also the parabolic dish icon flashing is not visible when i change satellite.

How resolve?
