Bootstrap full screen modal right side error - css

Question

Was trying bootstrap full screen modal. I can see the modal but there is space on the right hand side. It is not expanding the whole screen. The same code works when run individually as show in this link: https://mdbootstrap.com/snippets/jquery/mustafaozkaya/789907?action=fullscreen .
But when i integrate with my actual code this mess is created. Check image how the modal look with bootstrap and css code.
Please see below image:
Check the highlighted area.
Below is the code:
.modal-dialog-full-width {
width: 100% !important;
height: 100% !important;
margin: 0 !important;
padding: 0 !important;
max-width:none !important;
}
.modal-content-full-width {
height: auto !important;
min-height: 100% !important;
border-radius: 0 !important;
background-color: #ffffff !important
}
.modal-header-full-width {
border-bottom: 1px solid #9ea2a2 !important;
}
.modal-footer-full-width {
border-top: 1px solid #9ea2a2 !important;
}
.row > div {
padding: 0 5px !important;
}
img {
margin-top: 8px;
vertical-align: middle;
}
