It's in the wrong position for solid fuel, but in a good position for burning wood when the bottom vent is closed.
Top air for wood, bottom air for solid fuels.
Again preferably when it's cool, try and get that top vent moving. It might need wiggling or bashing with something to free it if it's stuck. Tap it with a chunk of firewood to see if it will move while hot, but don't break the stove glass while doing this!
Don't you have a pair of fire gloves? Handling a hot stove without them is asking for trouble. They don't need to be fancy branded ones, I use welding gauntlets bought from my local builders merchants.
