Render Essential Graphics with expressions

Hi, I made an Essential Graphic in After Effects. It has to be dynamic to the text length, so I used the exxpression "content.size".

So when I insert this Essential Graphic into a sequence in Premiere Pro, it works correctly. But when I render it in Media Encoder, the elements are scaled too small. I have to render it inside of Premiere Pro to make it appear correctly. 

So I assume, Media Encoder does not have access to the right data with expressions.

Do you noticed similar problems? Do you know a workaround I can implement into the Essential Graphics to make it render correctly in Media Encoder?

I have installed After Effects 16.1.3 and Media Encoder 13.1.5.
