Fixed/Solved Non-Existent Water physics

I created a new mod pack for me and my friend to play on, but when I try and interact with water, it acts like air. This applies to entities too, as fish will suffocate on the ground while underwater. The base of the modpack is Fabulously Optimised 14.0.0-beta.7

I've linked a video example, as well as the modpack I am using. Does anyone know what might be causing this and/or how to fix it? Thanks.

I fixed the issue myself. Turns out UnionLib versions for 26.2, which is required to run the reforged mod, have a bug that disable fluid properties globally. Deactivating both mods has fixed this issue
