Issue exporting SVG file

Hey so after creating a logo for a client and trying to export as a SVG, I found the file was all messed up. The black background was shrunken and flipped upside in the bottom corner and the graphics in other parts of the image were screwed up as well. I created a lot of the image in another program (procreate), converted solid color pieces to SVG and imported into illustrator. Some of the more complicated parts I image traced to convert into vector graphics. PNGs and PDF seem to be exporting fine and only issue seems to be with the SVG. I'm stumped so any help would be really appreciated. Thanks so much!
