Self-Uprooting Wheat Seeds

Location:My new Windows 10 Edition Realm. Conditions:Survival;Peaceful. Realm Age:New,1 Week old. I have two 9x9 wheat plots with a water source in the center of each one. I have planted wheat seeds at these locations several times in the past few days with no problems. Yesterday I found 5 blocks in a 2x3 area of one field only, in which the seeds "uprooted" and were floating above the ground, the soil still "hydrated". I attempted to replant the seeds but they would just uproot again within a span of 1 second up to a few minutes. At no time did the seeds develop to the next stage of growth. I removed and replaced the soil and used a hoe to till the soil. I then waited for the soil to get hydrated, determined by the color of the soil getting darker. I then tried to replant the seeds again and again the seeds popped out of the ground. It has happened to only these 5 blocks and nowhere else in my fields.
