Broken layout after uploading slides to LMS

Dear All,

You have helped me a lot already on various different topics, however I need your assistance one more time. In one of the trainings I have created, layout of the slides breaks after uploading to the LMS. Strange thing is that it breaks only on several slides, not all of them. All of the slides are based on the same template, reoslution is inherited on all of the slides. Any idea where to look for root cause of this? added screenshot for reference

thank you in advance!
