You have to remember that at that point, we only saw Fiona's power one time and haven't seen or heard much about her powers so we can't say for sure she got her Teleportation/Swirl Teleportation power from the Vortex Viribus even if she mainly used portals and used that power after tapping into the power of the Vortex Viribus. It could be a number of things like preferring to teleport through portals and etc. (not speculation) Saying she got them from the VV is speculation unless it was actually proven either by a character and/or cast/crew member.
If your proof is she never used it until the Vortex Viribus (despite the fact that she hasn't used her powers that much anyways) then what makes you so sure she didn't gain Telekinesis from the Vortex Viribus? She didn't use it until after she tapped into the Vortex Viribus, so that would mean she gained it from the Vortex Viribus right? I'm not trying to be rude or nasty about it, just curious.

Hello, you have to specify as soon as possible Charmed Ones have resistance against what? Or differently your edits will be cancelled. And please don't confuse resistance with immunity. You need try to be as specific and attentive in your edits in the future. Thank you for listening.
Help is good, but you are a little confused one power with another power. The sisters have no resistance, but immunity to Sirens' songs and to Pixie Dust. Immunity is a more powerful version of Resistance. I hope you realize it now ^_^
