Cheryl,
For starters, your Chia Lin looks great, as others have stated. I'm hoping that your sheaths...both from the most recent growths and the slightly older growth will all bloom for you this coming bloom season. I word it that way because mine bloom in January here in south Florida where they are basically grown outdoors in a shade house all year.
I have 2 of them, one a seedling and the other a mature plant. Over the growing season I usually get two sets of pseudobulbs produced, just like on your plant. The sheaths on the first pseudobulbs end up looking dried up (or blind) until buds start to form in all the sheaths at the same time...then get ready for a show! You're not too much farther north from me, so maybe yours will bloom in the winter too, and you won't have to wait till spring!
Bearing in mind that many cattleyas only bloom once a year and at the same time of year, I've learned to never cut off what looks like a blind sheath...not that they don't happen, but one never knows if there's a dormant bud hiding down inside.
