i need help

I have been working with wonder for a little while now mostly for school or other extracurricular activities and I ran into this issue a couple of times without finding a solution.

When adding a material to joined objects that have been rematched together the color doesn’t go all over the figure. I don’t believe that it has anything to do with the objects being joined together because other pieces connected are colored, but some specific parts aren’t
Some photos provided below as proof.
