Bug: Hitbox still active even though the object already gone

Hi, 5 years ago I'm creating a modified Stroop task for mobile phone usage. The task is not very different with the one existing in PsyToolkit experiment page. The only different is graphic design, and extra 4 button for response (answering what color appear).

Past 6 months I come back to make a shorter version for showcase purpose, but the the bug appear.
Here's my code (sorry for the language, but hope you guys get the logic)

 merah2

 biruhijau # this is two words combined, means bluegreen. This is for task 3, guessing the color with different text label than its color

Bug detail:

• The order is: first instruction, then first task, this is block one; end of first instruction, second instruction, second task (this is block two); end of second task instruction, third instruction, third task (this is third block)
• The bug appear in instruction 2 and 3.
• So when instructions appear, the former K button area hitbox still active even though the K button already removed. And instead of the bug recording response, it acted like start button: skip all the instructions and start the task rightaway.
