90d too dark in HDR


I’m really having issues with the 90d In-camera HDR. My subject is an interior room in afternoon light with large windows for natural light. Using a manual lens, I’m setting up for AV assuming if I set the ISO to 100 and the f-stop to 8, I’ll only need to be concerned with shutter speed. Using spot metering, I note that the dark is coming in at 0”8 and the bright is at 1/5, I’ve set up for both 3 and 5-shots at +-2ev and the resulting hdr image in both shots come out well-exposed for the highlights but too dark in the remaining areas. Am I doing something wrong or is the hdr function known for this?

Is it the same for a full-frame as an ASPC?
