Hacking Question Uninstalling specific tickets/overwriting tickets

[nachuz]

Hi guys, as you may know, a Smash Ultimate nsx was uploaded... and I commited the error of installing it after renaming it to nsp

Now I have a trashy ticket on my console and tinfoil doesn't let me uninstall that ticket since the list only let me uninstall specific title's tickets

I have 4 questions to know if I can solve this:
1.-Does nsps of games overwrites tickets?
2.-Does XCI files(Using SX OS) use system tickets?
3.-Is there any way to uninstall specific tickets that actually works fine?
4.-I have a nand backup from september, if I install it, does the ticket disappear?

Just found out that SX OS installer, not matter what, always installs the ticket, even if a game is already installed
meaning that no problem
