Font & style changes in the Dynamic PDF creation

Hi Team,

I have configured the dynamic PDF delivery in a campaign where I am able to generate the dynamic PDF with personalization columns. But for 1-2 personalization values the font is getting changed automatically.

If I am manually assigning the font in the ODT file using HTML font tag or changing the font from ODT file properties. Then it is passing the undefined value for that personalization.

Can anyone please help me to solve this issue?
