Need help with small studio room.

[SOLA]

Hi all. Need some help
I have just moved into a new room in a new house.
This is one of the smaller rooms i have worked in.
And it is getting on my nerves.
I have some basic treatment, the nipple type foam in most of the important areas. Rear corners behind monitors, ceiling above my head, sides of monitors.
I have used a lot of this in past in bigger rooms and it worked well.
Now I am in a smaller room, I seem to be getting some horrible reflections.

Mostly bass mids!
Here are my dimensions.
Room:
14ft long
7ft wide
7ft high.
Wooden floors.
I have placed a large rug under where I sit and listen.

The monitors are:
2.5 ft from the rear wall
1.5ft from side walls.
and i have them in a 3.5 ft listening triangle.
I sit at the 7ft point of the room, half way mark.

I am monitoring with Dynaudio BM5A, mid/near-field monitors.
Questions.
First of all, I am going to get a proper treatment kit.
How should I place the kit?
At the moment I think I have over deadnd the room.
I do not have rear bass traps.
I also have two large foam wall type things on either side of me so I can track without reflection.

I have read you should sit at the 38% mark of a room.
Should I move the monitors and myself closer to the rear wall to get to that mark, and keep he 3.5ft triangle?
Or reduce the triangle and move closer to the rear wall?
Etc
I always assumed it was important to keep monitors away form the rear?

I will try take some pics.
I the iPhone camera is rubbish, and my room is very dark.

Any advice would be greatly appreciated.

Thanks

Pics.
Sorry for the terrible pics
The red panels are the nipple foam framed with fabric over them.
All hand-me-downs
The rear area is pretty bare.
