Filters Module

Hallo everyone.
I am new to OpenCart and i have been using for a while. I love it. It's fast and easy.
I have a problem with the filter module and please, i need you to help me.
I have install versions OpenCart 2.1.0.2 & 2.2.0.0.
I found the following steps for beginners to make 1 filter (for training).

1. Go to Catalog > Filters and select Insert to create a filter group. Assign a filter group name (e.g. Color) and add filter name values (e.g. Blue, Red, Yellow).
2. Go to Catalog > Categories and Edit a category. Under the Data tab add the filters you want to be able to apply to that category (e.g. Color > Blue, Color > Red).
3. Go to Catalog > Products and Edit a product. Under the Links tab add the filters which apply to the product (e.g. Color > Blue). Apply to as many products as applicable.
4. Go to Extensions > Modules > Filter. If not installed select Install. Click Edit. Click the Add Module button and under Layout select Category and set Status to Enabled. Set whatever position and sort order you would like.

To the step 4, after the install click Edit, and i see ONLY the choice to Enable or Disable the module. Nothing Else. I don't know. Do i something wrong? Need to install something more?
Thanks and Sorry for my bad English.

After you enable the module, you assign it to a layout in System > Design > Layouts (or Design > Layouts for later OpenCart 2 versions). That's all you should need to do.

Thank you !!
