After playing and placing lots of blocks (like a roof). Any further drops do not show

After about 5-10 minutes of placing blocks and removing ones placed in error. For some reason when destroying blocks, torches or anything that should result in a drop, does not actually drop the item to pick it up.
Evidence at 40 minutes when I start placing glass panes: https://mixer.com/dannydaman9?vod=26679807
N.B. Silk touch allows the drop of glass panes and I double checked my pickaxe.

Notice that not all the glass panes are placed and then when removing some with silk touch after they don't drop.
