CBZ > EPUB "remove first image" issue

Bug Description

Hi, here is my problem:

I import zip files (containing images) in Calibre.
Calibre convert iot automatically in CBZ, adding the first image as cover, that's good
Then I want to convert this CBZ to EPUB, but I got twice my first images, even if I check the option "remove first image".

I read the description for this option, and It should work because that's exactly my usage (Calibre used the first image as cover, so I want to delete to first image to keep the cover and the following images)

Actually I have to delete the cover.jpg file in each folder (or edit metadata and delete cover) to not have this duplication

Hope I didn't misunderstand the option, and if yes, can someone help me with my 1st image duplication problem ?

I use Calibre latest verison, 64bit
Windows 10

Works for me, steps I tried:

1) Import a CBZ file
2) Click Convert
3) Tick the remove first image option under structure detection section
4) Click OK
5) Open the resulting EPUB file int he calibre viewer.
6) There is no duplicated cover. The first page is the cover from
calibre, the second page is the second image from the cbz file.

I'll put some screen of my options when I convert and evidences there is duplication

After importation I got this in the Calibre folder.

I convert to EPUB with these options




After that, I got this in my folder

But When I open the epub (with default viewer, that is Edge browser)
I have this

Twice the first page, even so I ticked the option.

And same with Calibre Viewer
page 1 https://puu.sh/x4zjf/e6f8f563c2.png
page 2 https://puu.sh/x4zjP/bdec268326.png

Am I misunderstand another option that create that duplication ?

Thanks in advance.

ps : I can't for now, but I'll add a conversion log asap.

You have the option in comic input to disable comic provessing turned
on. Tyurn it back off and you should be fine.

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.

OK so I need to turn off that option, but it was to not resize/change to black & white, etc (the other options on comics input.)
I need to turn off and select whet I don't want to be processed ?

I'll try that, thanks a lot.
