Entity levels and water catchers

Had a player report a level 20 small water catcher is outputting the same as a level 1 small water catcher
I've taken a look and found they are correct, the output from both is the same.

Also found, small water catchers output water faster than large water catchers, and that their water generation is static regardless of the weather but it should change and generate vastly more water when raining but instead they always generate 38 and 114 or multiples of that based on level

Finally, not sure if you're able to do anything about this last part but the capacity bar in the UI of a levelled water catcher shows it's full once it has the vanilla max capacity 10k/50k even at max level
