If you are using Insert Split Marker - what text is shown for it in Code View?
The name used for the split marker has changed - but it should still pick up older split marker names.
The old name sigilChapterBreak doesn't work in this release. We'll make sure it does in the final. For now just use the new marker class sigil_split_marker instead and it should work fine.
