As the title suggests, have a phal with a solid cylindrical leaf. Assuming this isn't normal and probably a deformity. My only experience with leaves opening as they grow has been with my bulbophyllum which was completely flat until it opened fully and even when it was closed it had a line running down to the base of the leaf where it was going to split.
One other leaf has these ridges on it.
Pics attached. Just curious what you think it is and what should be done about it
Maybe you can use a very clean set of scissors (sterilised with some fire, and then cooled a bit) - then snip down the region where it normally should have a gap. Some minor surgery maybe. Just make sure snipping down the shaft is done real carefully - ensuring it doesn't snip any newly developing juvenile leaf that might be down in the depths.
Otherwise - just allow the leaf to stay like that. A new leaf may well push up and through as Ray mentioned.
Interesting how the phal leaf is looking like a water hyacinth.

I have a Phalaenopsis that did this too although the “tube” on mine is shorter. It’s growing a new leaf right now and the tube is slowly splitting as the new leaf grows. I was thinking I might need to do some surgery but mine ended up having matters in hand with no intervention required. I’d leave your plant be and wait and see.
