Mined Blocks Float and are not retrievable

Coastal Village Seed (-1813740965); Survival Mode; Normal Difficulty; Infinite World Type. I am using a PS4 Controller attached via USB 3.0 Port.
Mined blocks float, but they are not retrievable or added to inventory, see 4 Attachments. The first screen shot shows items dropped into the water by a witch which could not be picked up. The final 3 examples show cobblestone and sand floating above the floor. The floating blocks can not be picked up . I Saved and quit the world. When I re-entered the world, the floating blocks were gone.
