Trying to create an Automator workflow/quick action to convert a pdf to cbz

Hello,

I am currently trying to convert my digital comics from pdf to cbz files, for which the automator actions are super handy. I got to the point where I have the workflow create a zip file with all the images inside of it. There are only two problems I have:

1) The first image is not being numbered at the end (example: [comic name] Volume 1, while the other images come out as [comic name] Volume 1 [image number]). This causes the cover of the comic to be the last of the images.

2) The zip is not being converted to a cbz file in the end.

Any help is appreciated.

This is my current workflow:
