What happens to the output through foreach?

Question

Smarty

I output: {$item|@print_r}
I look through the source code:
https://dropmefiles.com/7Y0Qt
I look through the developer panel:
https://dropmefiles.com/v4B5G
What's going on? There is more data through the source code than through the panel.
Trying to output data from [ELEMENTS] - error
