Spelling mistakes at RTBF

What is happening with the RTBF editorial staff? Almost every day I discover fairly serious spelling or grammar errors.

In this case, the two past participles in the highlighted sentence should be infinitives.

"(…) which sees 400 trains passing by and around twenty thousand passengers traveling."

I wanted to report it to the editorial staff, but to be able to do so they require the creation of an account and giving lots of private information, including their address.​​
