Getting font size from a text layer

[Heyoz]

Hello, i'm making animated templates with a base text that can be changed directly in Premiere Pro as a graphic element.
However my base text gets duplicated in the animation. So no worries i just use the string and get it from any duplicates to the original source text layer. And like that i can change the font, the style, etc... Everything works. EXCEPT the size of the font, and i don't know why. I can't seem to find an expression either to do what i want to, so i'm posting a request here 😞

This first screenshot is my text being nicely duplicated but smaller, because i changed the font size of the base white text after doing it.

Just an explication of what my animation is, with mask and stuff the color change, but it's the same text, wich work as long as i don't change the font 😕 

This final screeshot is where i change the font when i export the template for Premiere Pro, but changing the size doesn't affect the other layers :(.  

Thanks in advance for anyone that take times to reply.

Text style expressions have limitations. Instead apply a text animator that controls the size and wire up that.

Hello Mylenium, thansk for your answer ! 
But i don't see what you mean, sorry. Do you mean like a preset wich is already in After Effect? Or a plug-in animator?
