marine fish feeder not working

[Sebrim]

attenborosaurus, dunkleosteus and tylosaurus are starving to death, can't get them to use the fish feeders, for the dunkleosteus had to put shark feeders as an alternative, but no matter how many marine fish feeders I put they don't interact with them
had other 3 pools with elasmosaurus/archelon, shonisaurus/ichtyosaurus and kronosaurus and they all work well
