What you were expecting to happen, and what actually happened:
In battle, we hold L and press ABXY to access our own troops.
If we then release L /before/ releasing A or B, the game reads this as an additional A or B button press input, causing the A spell to misfire, or unintentionally backing out of the troop screen respectively.
How often does this happen? When did it begin happening?
As this is not really a bug, but rather an issue of unfriendly / confusing UI design / implementation, it happens 100% when the button sequence is pressed in battle. (In the case of L + A, the spell fires off if it is mana charged.)
