"Blur area" feature not working consistently in Captivate 12.6

I have a 4-module course that includes software simulations. I have to blur out personal information on the screens. On some modules, the blur area function works fine, but on other modules, it's hit or miss. I'm working my way through the SCORM output on my LMS on the 3rd module, and none of the blur areas are showing. I can't expose the personal information, and I've only been able to correct this on previous modules by downloading the background, blurring the info in Photoshop, and replacing the background with my correctly redacted version. I don't have time for this. Has anyone else come across this, and is there a solution?
