Hi. You not specified site you tested extension with. Please check if extension is compatible with specifed site you testing it https://kellydownloader.com/crawlers/ and how to use it exactly (there is many video examples of use cases). Its instrument for capturing images data from sites, its not suppose to "save all full resolution images" by one click and you need to check \ find possible work pattern for your case. Some patterns can be deprecated during time because specified site can update its layout. If you interested in support, adding or fixing full resolution detection on specifed site you can report problem here, on github, or by email.

If you have questions about how to use extension, you can just write on email torrenttvi@gmail.com Dont need to mislead people about functions

If I understand right what you trying to do

1. Edit \ delete functions needed just for manual single edits, you dont have to use this functions for filtering and download.

2. You have "deselect" option in Download section. Also you can deselect \ reselect all at once if needed https://catface.ru/userfiles/media/udata_1652868943_bbojhrko.png

3. You can specifiy elements by range or by specified number in current filtered images by its #Numbers in "Elements" field in download options section, create new profile from this selection if needed by click "Download as profile"
