Stubborn duplicate cover in ePub t0 Mobi conversion

[dvpzoey]

Hello everyone,

Some EPUB to MOBI conversions (in Calibre) add duplicate cover in the MOBI output.

'Structure detection > Remove first page' doesn't help too in this scenario.

If I just delete the 'Cover.jpg/MSR-cover.jpg', it leaves a black rectangular border at top on that page.

However, if I delete the cover.hmtl file altogether, it solves the problem. This way MOBI has a single cover.

Only downside obvious to me is that there is no 'Cover' title in the Table of Contents.

My question is does deleting the cover.html poses any problem in rendering the MOBI on Kindle devices? Is it okay to delete Cover Html file in this scenario?

is there any solution to this problem? If anyone interested, I would be happy to send the EPUB file. (less than 1 MB)
