Spectrum Guide Remote has too many IR codes for buttons

[InternalError]

I am trying to configure the Spectrum Guide Remote (Charter Spectrum URC1160) with Flirc Fire TV Edition and it seems like I have to set each button a large number of times. I read this part of the troubleshooting section which says to do each button twice for remotes with alternating patterns for every successive button press, but this issue I'm facing is different. I think depending on the distance and angle, there are different IR codes for each button. This doesn't happen with a different Sony Universal remote. I eventually run into the "No more space for new buttons" problem trying to save the same buttons multiple times because of this and still can't use the remote properly from certain distances.
