Where did you get the MLA output style and did you or someone else modify it?
If it is “out of the box” and unmodified, it looks like the problematic references are with specific reference types. I see that the space is missing for Audiovisual Material in the MLA style (see image 1), which is probably the ref type you used for music CDs? Spacing issues are probably due to the chosen ref type and empty fields being incorrectly “punctuated” and missing or incorrect application of the “link adjacent” or “forced separation” characters.
Which ref type is the Dairiki reference? (extra period) and the title capitalization is a setting in the bibliography template too. see image2. I also changed that in the attached output style to “leave as is”.
so output style may need further tweaking, but here it is. see if it fixes things. remember you have to save this from Endnote (default setting) and then view the style lists and select the modified version in the word document on the endnote ribbon/toolbar.
