Border padding in Blender 2.82

Hi all.

I have an issue with the fluid not filling the container that I have created. Rather, it leaves an empty border.
There is a gap between the fluid particles and the fluid Effector.

I have looked all over, but I can’t seem to resolve it.

I have tried scaling up, changing resolution division and a variety of tweaking.
Help in resolving this will be appreciated.
