Cannot individually remove and/or place/store items from bulk

What I expected to happen was...:

Say that you have a slot containing 64 bricks in your inventory and you'd like to remove ten. Normally, you'd press the appropriate button and you would be able to remove that number for whatever purposes you have instead of removing them all from your inventory at once. You then would be able to individually place them into the appropriate slot on the crafting table to make an item.

What actually happened was...:

The function that normally allows this process nolonger works. I've tried this with different controls, even creating new worlds, and nothing has changed. I can only select all of that item at once or none at all. I also cannot place or store them individually in my inventory or the crafting table; the game only allows me to place all of that item at once. This naturally makes crafting an item that requires more than one of the same ingredient in a particular arrangement - stairs, for instance - so difficult that it is practically impossible especially for new players. This never happened until the latest update, as this function worked perfectly fine before I installed the update.

Steps to Reproduce:
1. Choose an item that you have multiple of - e.g. 12 cobblestone for example; the number does not matter so long as you have multiple of it.
2. Try to individually remove one or more of that item from your inventory.
3. The process will not work; it will only allow you to remove all of them using the regular control key or none of them.
4. Try to place one of that item that you have multiple of from your inventory into any slot in either a chest or crafting table, for example.
5. The process will not work; it will only allow you to place them all at once or none of them.
