Water duplication glitch while trying to bucket an axolotl

When I try to pick up an axolotl, it won’t go into my bucket, but instead, it creates water into my bucket if it is empty. I saw an axolotl on the ground so I placed a water bucket to try to get it to swim so I could pick it up in the water. What actually happened several times, is that the water stayed and the axolotl glitched and it stayed too, which created more water “blocks” around on the ground
