Hi, i'm playing on the 1.21.4 version of the mod, (thanks again for reviving it, it is amazing) but when i'm dropping dynamite, when it's in the water, they do not disappear after "not explosing" and so there is still red sticks left on the blocks, they are still under the influence of gravity, but it's not possible to destroy them.
Even with regular Dynamite, the sticks are not vanishing.

Just checked - in my client they are disappearing. It's probably some other mod that prevents them from disappearing...
Also, please keep in mind that they need a minute or so to disappear - they do not vanish instantly!
