Consider letting them be for awhile. They may be bloom stalks- which can be safely cut off if you don't like them (won't hurt the plant) or they may be the start of new leaf stalks, which you would want to leave on. Hard to tell by your description
It's kind of late in season for either one, but there are many perfect little spots in TV that heathy, more tropical plants thrive in- they won't even slow down when it's cold.
Ti plants can sometimes suffer over winter- they are not super hardy here, but I found that if they look bad but are still alive, the stalks can be cut back in spring- even down to the leafless parts- and they will sprout anew.
My neighbor had a cluster of three that looked pretty bad by the end of last winter. He wanted to yank them. I convinced him to cut each stalk a different length- short, med and taller.
He had three sticks for awhile and kept giving me 'the fish eye'- but soon they were glorious. He's quite happy now and won't hesitate again, if they get crispy or drop their leaves over winter.
