Index "See" and "See-also" formatting

Can someone point me to where I can address the following changes that I need to make in the FM Index file? We have some other products that work as desired but I can't figure out what is different between the 2 products.

Currently, there is a comma after "charter" but I need that to be a period and "See Also" should have a lower case "a" in "also".

• charter, See internal charter
• See Also risk

Dita:

<indexterm class="- topic/indexterm ">charter<index-see class="+ topic/index-base indexing-d/index-see ">internal charter</index-see>

<indexterm class="- topic/indexterm ">risk management<index-see-also class="+ topic/index-base indexing-d/index-see-also ">risk</index-see-also></indexterm>

It should be displayed as:

• charter. See internal charter
• See also risk

Thanks.
