Hi mate, don't worry.
May you send me a screenshot of the screen were it is indicated the thing about the custom list?
To take a screenshot you need to do what is indicated in here.
To send a picture in the community from your phone click on the camera icon while being on the page to reply to this post.
an option saying choose an action will come up and select archive app (the folder sorrounded in yellow), then under the categories voice click on pictures and then there should be a screenshot folder, into that you will find the screenshot you took and you can select it to send it.
To avoid sending personal data before sharing the screenshot you can go into the gallery and then in the screenshot folde.
click on the screenshot and at the bottom there will be 4 icons tap on the one with the pencil, then you will get into the editing menu.
To write onto the photo slide the finger on the are on the botton which has a few icons (T, sticker like thing) at the end you should be able to see a painter's palet. Click on that an now you should be able to write on the photo so proceed to obscure contact names ect... after you finished click on save and then send the pic here.
Sorry for not being so clear,
We should be able to fix everything,
have a nice day
