[openrailwaymap] Signalling rendering and legend translation

Hi, I recently started to improve the railway data and tagging in Sweden, particularly around the Stockholm area. However, I have noticed that the Swedish translation of the legend at openrailwaymap.org is in some cases missing, wrong, or misleading. Is there a way I can improve the translation? I also see that the signalling map style does not show anything except ETCS in Sweden. But most parts of the railway network is equipped with the ATC signalling system. And the map data is also correctly tagged for this. Is there a way to include ATC in the signalling map style? Regards Patrik
