Heyas! Thanks for pointing this out.

Your comment has made me aware of how weirdly I mapped this sign.
I used a JOSM traffic sign preset for tagging this, and it seems I applied the 
Spanish-style orientation in city sign preset, when this sign is a Catalan-style orientation in city.
The difference between the two is that the Spanish-style is colourful and bigger, while the Catalan-style is mainly in boring white background.

This sign has nine panels of destinations with different arrows, text and icons each, so it would be impossible to condense all of this into 6-ish or so tags.
The traffic sign OSM wiki page says how to map traffic signs in general (as in orientation, if it's in a pole, etc.), but not what values to use in each sign, so it doesn't help in this case.

Also, looking at the tags it put out, it seems to combine roundabout-like exit with numbered destination panels in a weird way.

I'll remove the tags and refactor this sign in an upcoming changeset.
