ROKU streaming stick 4K (Dolby Vision) Autodetect malfunction

When set to “Autodetect” my tv reflects Dolby Vision regardless of the resolution transmitted by the program, i.e., 720, 1080,4K, 4K HDR, 4K Dolby Vision. In order to watch the program in it’s intended resolution I have to go into settings and manually change it to the proper resolution.  How do I get “Autodetect” to function as it’s suppose to?  I have a ROKU Streaming Stick 4K purchased about a month ago. It’s inserted directly into the HDMI (ARC) portal of an LG OLED 55CX. I have an LG OLED 65 with a ROKU Ultra with HDR capability. When I set it for “Autodetect” it functions properly. Anyone have any ideas on how I fix the problem with the Steaming Stick?
