Custom Content and Translation

Hey there,
I am having troubles translating some strings of the plug-in.
I used Loco Translate plug-in but even though I see those strings translated within Loco, they still show up in English on the front-end.

Also, I used to embed iframes with the old version of Directorist, now I need to use the Custom Content to make the iframe show up, BUT it’s the same for all listings, while I need it to be unique and different for each listing. How do I achieve that??

Thanks in advance!
