Filter Creation - Fields, Features Missing

I need to create some filters on both product fields and features in 4.3.3 but they are not present in drop down list for filter creation. Is there some way to add them or should they be present automatically? If that is the case, how can this be fixed? I am wondering if others have experienced this problem or if my installation somehow got damaged. Any insights appreciated.

What product fields and types of product features do you want to use for filters?

What product fields and types of product features do you want to use for filters?

Product fields: Price (**)

Features: Height or Width (**), Age, Eye, Hair, Sculpt, Artist, Brand, Medium, Edition Type, Edition Size, SKU (*), UPC (*)

(*) = only one product will have either of these values so maybe better as search rather than filter if there is some reason to limit number of filters.

(**) = numerical with continuous range, all others are text.

Shouldn't all features and fields be listed as choices on the filter creation page?

Only the following feature types are supported by filters:

- single checkbox

- multiple checkbox

- text selectbox

- number selectbox

- brand/ manufacturer

- number
All other types are skipped

Thanks for info. It is now being done with fewer filters.
