Farm/crops won't grow

When I build a farm, the farmland doesn't appear to get "wet", even when directly next to and surrounded by naturally spawning water. It has direct sunlight most of the day and is surrounded by torches. About 10 in game days have passed since the original crops were planted, most of that time with player nearby. Using bone meal still produces crops appropriately, but they won't progress to the next growth stage naturally.

I've tried this with wheat seeds, potatoes, carrots, melon seeds, beetroot seeds, pumpkin seeds, and sugarcane, to no avail.

I've also looked into if I just messed up the settings or cheats, as I did some screwing around with those at the beginning of the world, but I can't find any reason for it. It may be worth mentioning that this world was originally generated in 1.7 (I think?) and then shortly afterwards opened in 1.14.4 because I didn't realize I had opened an older version.
