An example of the open file after hitting show forms

SUMMARY

At the following website, various PDFs are made available, many for free. These PDFs have PNG (?) images stored in them that can be cycled to adjust the color scheme of the images.

https://printableheroes.com/

When hitting the cycle button/form, the image attempts to change but does not properly replace the previous image. Instead it seems to paste the next image on top of the previous image. 

STEPS TO REPRODUCE

1. An example download link can be found here in the top right corner: https://printableheroes.com/minis/492 I attempted to copy the download link but it appears not to work independently of the website.
2. Open the PDF in Okular
3. Turn on Show Forms
4. Attempt to click the "click to cycle" or "click to select a base" button.
5. After the first click, the image will appear stuck and duplicated.

Accidentally hit enter. Other info:

EXPECTED RESULT

I am expecting the initial image to disappear from the PDF and the new image to replace it. A second click of the button I am expecting to either cycle to the next image or back to the first image, properly replacing the previous one in the cycle.
