Losing movement option after standard attack. Can only 5-ft

Platform: Steam Windows 10

Do you have any mods? No (unless portraits count)

Please explain the issue is in as much detail as possible:

I’m trying to figure out why I’m losing my movement option after I attack sometimes when using the turn-based mode. I don’t lose my movement action like drinking a potion. Just the movement. It felt like the game was treating all my standard attacks as full attacks but when I highlight an enemy it gives me my full movement speed. Below are some screenshots.

I am experiencing this very thing as well. Performing a standard action before you move makes it so you can only 5’ step after the standard action rather than being able to use your movement action in turn based mode.
