sickly phalaenopsis orchid

[Hazza]

Hi everyone, new member Hazza here from the UK, hope you’re all doing good.
So my first post I have a few questions.
This phal orchid that I have is not doing too good, all the leaves are wilted/drooping and have been for months.
It doesn’t seem to be dying but isn’t putting forward new leaves either, however it is producing new flower spikes which all tend to die back after a few weeks.
Also one of the off shoots is producing sticky sap, should I cut it back?
It is on a sunny spot on the kitchen window with filtered light, and has been on a drip feeder, and is watered very sparingly as it is in a glass bowl, it has been repotted recently and I’ve cut the dead/mushy roots off and it had a few healthy ones left.
Is there anything more I can do to help it recuperate? Is it worth persisting with?
Also it has 2 conjoined crowns, is this usual?
Sorry for the long post! Any tips would be appreciated, thank you.
