Replay button jumping too far back

Since the last update, when the replay button is pressed quickly several times, instead of jumping back 6 seconds per press, it jumps back to the last tick mark. This occurs with both recordings and live TV. I believe this is the only button with an issue. 

I’ve contacted DirecTV several times. They replaced the Genie Mini and the triangle tower-shaped device, but neither fixed the issue. As a bonus, I lost all my recordings and settings. The remote is an RC73, and I’ve tried three different remotes—all with the same problem. 

Additionally, after navigating back to where I was, I often experience pixelation and audio problems for a few seconds.
