Right To Left (RTL) text formatting does not apply for 'Collage' Image Style

Site URL: https://www.careme2.de/fa/home/

Dear community, 

first of all, thank you for the help received so far!

Here is another item I would need help with...

I have a dual language setup and this page https://www.careme2.de/fa/home/ which needs Right To Left (RTL) text formatting, so I added the following code via "Advanced":

<div dir="rtl"</div>

Everything works fine and text formatting changed to RTL, besides for the text for the two images which have the 'Collage' image style (see screenshots attached). 

Is there a way to change the text formatting to RTL for those two 'Collage' image blocks (or actually any image blocks used under the second language sub-pages under /fa)?

Thank you!
