Regarding Micro Front End(MFE) component in AEM exported to Target

Hi Everyone,

We have MFE component exported in Target as an Offer from AEM. 

While adding this MFE component in activity there no content showing of MFE, but when we live the activity and load the page it's showing.

My question is why MFE component is not showing while creating the activity in compose mode or browse mode?

Regards,
