No need to worry about the AGC which is the Automatic Gain Control and your receiver regulates this as to not swamp the tuner. The one to concentrate on is the Signal to Noise Ratio which relates to the Picture quality.

From what you are saying and i have seen this on other receivers sometimes its a driver problem which will not display the correct AGC percentage of the current satellite transponder's.

The loss of channels could also be to the day to day changes that $ly appear to be doing on a daily basis which an up to date channel list could solve, worse case scenario is your dish has gone out of alignment and will need re-doing.

No Problem like i say the AGC is not that important as the receiver regulates the amount so as to bump up the SNR if its low or lower it if the SNR is too high.

Good Luck with the Dish
