For loops cause issue with numbered bullet points

**Describe the bug**
If a for loop wraps a number of sets of bullet points then every iteration of the loop produces a number incremental from the last.

**To Reproduce**
So we have a for loop around a 2 page letter, within the letter exists a numbered list. When the second letter merges it produces numbers that continue from the previous letter.

**Expected behavior**
I expected this to restart the numbering on every new merge.
