I noticed a possible glitch at wikipedia api prop=excerpts

In some cases, 

parameter exsentences does not return the number of sentences, but the coordinates of an article.

Instead parameter exchars return a number of chars, and also the coordinates.

E.g.

please have a look here:

http://en.wikipedia.org/wiki/United_World_College_of_the_Adriatic

http://en.wikipedia.org/w/api.php?format=jsonfm&action=query&pageids=1266661&prop=extracts&exintro&explaintext&exsentences=10

I would like to have just the intro with the sentences.

Another example, though I think this is not an error, is with names, e.g. 

H. P. Lovecraft: Against the World, Against Life

http://en.wikipedia.org/w/api.php?format=jsonfm&action=query&pageids=17545993&prop=extracts&exsentences=2&exintro&explaintext

Here I obtained a truncated sentence, cause the dots in the name force the sentence to be truncated.

Is it a fix to do?

coordinates should appear only with their module, right?
