Good evening. Checked the svg. That part which you see visible is the image part of svg that start with something like <path fill="#FFFFFF" d="M567.271,807.32h-5.801c-0.557,0-0.834,0.316-0.834,0.949c0,0.744,0.34,1.125,1.02,1.143h0.254 c1.055,0,1.861,0.418,2.418,1.256c0.551-0.838,1.355-1.256,2.416-1.256h0.809c2.01,0,3.016,1.01,3.016,3.031l-0.088,6.434h-1.758 l0.088-6.434c0-0.996-0.426-1.494-1.275-1.494h-0.791c-1.025,0-1.537,0.498-1.537,1.494v3.357h-1.758v-3.357 c0-0.996-0.514-1.494-1.539-1.494h-0.879c-0.85,0-1.273,0.498-1.273,1.494l0.088,6.434h-1.758l-0.088-6.434 c0-1.248,0.459-2.123,1.379-2.627c-0.334-0.41-0.5-0.926-0.5-1.547c0-1.658,0.857-2.488,2.574-2.488h5.818V807.32z"></path>
This can only be changed using an editor like Adobe illustrator or Inkscape or other svg editing tools. Once you remove them you can manually write what text you would like to see there. Those codes that you change may be for the program that reads it for processing purposes.
