Okay, I have solved problem number one.
Problem number two is when there are more than one dropcap styles in an epub, where dropcap2, for instance, is smaller than dropcap 1, for instance, it is 60px and dropcap 1 is 80px. I have tried changing the size but it is either as big as dropcap 1 (80px) or too small, like a regular letter. If I change the second-to-the-last (the 7th) value in the font size key in calibre, the fonts become the same size (dropcap 1 becomes smaller, assumes the size of dropcap 2).
I can't figure it out so please
