Java 1.14.3 Fish and Squids are not spawning again!

So apart from the Drowned I have not had any other aquatic mobs spawn in 1.14.3 so whatever was resolved in 1.14.2 to get them spawning has broken again in this update like it did in 1.14 and I fear it hasn't been addressed as it isn't in the 1.14.4 pre release 1 fixes list.
