Wrong playlist in embed code

[abraxasss]

Hi everybody ! Today I wanted to embed a playlist in my website and it seems there is a problem. To give you an idea: If I insert twice the same code, I get two different playlists in my page. If I insert one code, its the wrong playlist (when I click on <> button, it sends me to another playlist with a different code)

I tried cleaning my cache, restarting spotify and my web browser, nothing is happening.

This is very weird, I mean, it's an iframe, it should just work.

Any tips ?
