I was given a phalaenopsis with two stems last year and these produced 13
flowers which lasted 8 months. During this period all the leaves except one
died.

I cut the two stems at the second node after flowering. One stem produced
two flowers after 5 months and the other stem produced two buds which fell
off as they opened and that stem has now withered.

The stem with the two good flowers is now producing tiny leaves at the
second node where it was cut the first year.

What is happening and should I cut this off to make a new plant or what?
Help please.
