The positions are old and just carryover, the Clearwater graphic has Caicuto as a catcher and Kotowski as an infielder.
Looks like no one was put on the non-60 day IL for the rosters so any minor injury was assigned to FCL as well as guys still ramping up.
On the DSL side, I don't rank just signed players which keeps the numbers down preseason, the last guy ranked but not promoted from last year was Angel Liranzo who is a 17 year old throwing in the high 80s, but good command and feel (sort of a Ranger Suarez starter kit) and was expected to repeat.
