I printed Luke chapter 11 on its own using PTX print and two verses which were combined \v 30-31 along with the following paragraph break disappeared, so that verse 29 was immediately followed by verse 32. I tested this a couple of additional times with the same effect. Then I tested generating a PDF for a range of chapters such as Luke 1-10, and this time verses 11:30-31 showed up properly. I then tested the same thing on a set of combined verses in Mark and in Genesis, and the same thing happened. The combined verses were missing when generating only the chapter, but were visible when generating a range of chapters (even just two chapters).
