[Framers] Paragraph numbering

[DJ Layton]

I've been using FrameMaker since 2000, and I am puzzled with the result I'm getting in the 2020 version that I have now.

I started a numbered list, and inserted some indented alphabetic sub-items, then returned to the numbered list. I expected to get something like this:
1
2
3
a
b
c
d
e
4
5
6

Instead I got this:
1
2
3
a
b
c
d
e
6
7
8

The second part of the numbered list seems to be incrementing the ALPHABETIC value rather than the preceding NUMERIC value.

I used the standard <n=1>, <n+>, and <a=1>, <a+> building blocks.
I cannot figure this out!!!

Can anyone help??????

Thanks in advance.
