'When copying object from word to powerpoint the one transperent line is created

I have chemical compound editor - Biovia Draw 2021. And MS Office 365.

enter image description here example in word

When I copy any object created in Biovia from Word into Powerpoint the transperent line will be created above the copied object: pasted into powerpoint with line

Why is this line is created and is it possible to get rid of this new object creation?
