Does the problem with sticker placement still exist?

No. Product identification stickers are easy peel removable labels. Labels can be removed with little effort.

Would this be the appropriate calculator for flex ducting? It says round but I don't know if that's metal or flex.

This calculator is not for flex ducting. Flex ducting has a different friction loss and varies by manufacturer so there is no universal calculator that works for all flex ducting.
