C++ImGui not fitting window - c++

Question

I'm working on a simple GUI, though my GUI window is unaligned and I cant see any issues in the code. I'm throwing this out there in hopes someone has seen this before because im pretty new to ImGui and have been looking at this code for days lol.
this GUI is using direct x 9.
here's the main .cpp file.
#pragma once
#include "gui.h"
#include "imgui.h"
#include "imgui_impl_dx9.h"
#include "imgui_impl_win32.h"
