Adobe Captivate 7 - fonts of systemvariables were changed into the fonts of the Browser after publishing in the learning management system

Hello,

I use a learning management system to publish my e-learning courses I created with Adobe Captivate 7. Now I recognized that the fonts of my system variables I used e.g. on the quiz result slide (score, max. score, widgets message that the learner finished successfully the elearning changes from a sanserif font into a serif font (Times New Roman).

Is there a possibility to stop this replacement?

Greetings,

Erika
