Freeform drag/drop -preventing colors from automatically inverting

Hello all,

Step 1: I have created a freeform drag and drop.

Step 2: The user completes the drag and drop correctly.

Step 3: Since the user has completed the drag and drop correctly, s/he sees the “You’re Right!” feedback, clicks the “continue” button, and moves on to the next page

Step 4: When the user re-visits the freeform drag and drop, the exercise ‘remembers’ where the user placed her/his correct answer.

Here is my conundrum: in Step 4, the color of the text has automatically been changed. Same with the color of the textbox, which makes it almost impossible to read.

How can I prevent this from happening?
