I don't see a problem based on this info.
This is one of those posts where a pic would be a big help.
Large loop on the top limb as has been stated.
Serving should be more below shelf height than above. You have more fingers below and the lower serving is also there to protect the string from contact with your arm. Most squares also clamp more below than above so you need room for that. More serving should be below the nock point.
The center of the serving could be above or below the center of the riser. It makes no difference where the center is as long as you have what you need for nocking, fingers, bow square, and sting protection. The center of the riser could vary depending on bow design and how your are measuring. Are you measuring to some point on the grip or the distance from end to end of fade out?
Bows are different. I had a string made for a bow and then sold the bow. It was made to be just right for above and below the nock point for length needed without a lot of excess serving length and weight. I sold the bow. On a different bow I barely have room for top finger above the nock before the start of the knot. Works great shooting three under. Two different bows the same length and at least 1” difference in where the serving sets in relationship to the shelf. From that, you can take that the serving being centered in the string is not necessary the correct location for it dependent on the bow.
Honestly I have been shooting bows 40 years and could not tell you if any string I have ever had was served with the center of the serving centered on the string or the riser. I just know how much I had above or below my nock point to do what was needed. I have seen AMO strings with easily 2” more serving than needed. Necessary if the maker is trying to cover all bases, but I see no need for a lot of excess serving and weight. I order my sting now for a specific bow so I have no more serving than required.
