Could it be a mechanics of infinite water sources? When I was clearing monuments I had to use more sponges sometimes due to reappearing water sources.
This wasnt happening in versions from 1.14 to 1.14.3, but in 1.14.4 started happening again
You make want to back up your world.
While being in oveworld open your world to lan with cheats on, then paste this command:
/data get entity @e[type=minecraft:squid,sort=nearest,limit=1]
if it says:
"No entity was found"
then there is no any squid, but if it produces something like:
Squid has the following entity data: {Brain: {memories: {}}, HurtByTimestamp: 0, Attributes: [{Base: 10.0d, Name: "generic.maxHealth"}, {Base: 0.0d, Name: "generic.knockbackResistance"}, {Base: 0.699999988079071d, Name: "generic.movementSpeed"}, {Base: 0.0d, Name: "generic.armor"}, {Base: 0.0d, Name: "generic.armorToughness"}, {Base: 16.0d, Modifiers: [{UUIDMost: -7938775428015832883L, UUIDLeast: -9050083393751582449L, Amount: 0.010626721924974016d, Operation: 1, Name: "Random spawn bonus"}], Name: "generic.followRange"}, {Base: 0.0d, Name: "generic.attackKnockback"}], Invulnerable: 0b, FallFlying: 0b, PortalCooldown: 0, AbsorptionAmount: 0.0f, FallDistance: 0.0f, DeathTime: 0s, HandDropChances: [0.085f, 0.085f], PersistenceRequired: 0b, Motion: [-0.006131845060735941d, -5.81076426897198E-4d, -0.004541310947388411d], UUIDLeast: -4843752378479299375L, Health: 10.0f, LeftHanded: 0b, Air: 300s, OnGround: 0b, Dimension: 0, Rotation: [97.4675f, 0.0f], HandItems: [{}, {}], ArmorDropChances: [0.085f, 0.085f, 0.085f, 0.085f], UUIDMost: 6868144683436164223L, Pos: [11.002002046443522d, 1.1052815522998571d, 3.430051130708307d], Fire: -1s, ArmorItems: [{}, {}, {}, {}], CanPickUpLoot: 0b, HurtTime: 0s}
It means that there is one or more squids, you just have to find them. You may have to try this command a couple of times, best while being near some water.
