Bible chapters and verses differ with translations

You are not missing any verses. All the verses that you would find in any Catholic Bible (including the NAB) are in your Bible as well.  The issue has to do with the translation, and specifically how different translators interpret chapters and verses.

There may be differences in the text if you are using a translation other than the RSV-Second Catholic Edition. Bible translations sometimes differ in word choices, and in chapter and verse numbers, as these are not always standardized between translations.

I can only add that if you ever see a difference like this, you will notice that they are always at the beginning or end of a chapter, so if you look either right before or right after it, depending on which translation ended the chapter, you'll find the verses at the beginning of the next one or the end of the previous one.
