@Jasonlee6789 default is a empty string right now, https://github.com/OpenEMS/openems/blob/7ef6c74fb0f90b8d24f0fcef1d076e04fc53070e/io.openems.edge.evcs.cluster/src/io/openems/edge/evcs/cluster/Config.java#L16 so it is possible that the title is not set, it would be better if we touch the edge config instead, then we can also get rid of the https://github.com/OpenEMS/openems/blob/7ef6c74fb0f90b8d24f0fcef1d076e04fc53070e/ui/src/app/edge/live/Multiple/Evcs_Api_Cluster/Evcs_Api_Cluster.ts#L63

FYI @sebastianasen wasnt there a general change in aliases not being empty but taking the id as default?

If this previous international alias doesn't display, I find the bug is that we should use || replace ??, I have tried ||, it works, I will make a new commit.

Replaced ?? with || to handle empty string aliases, check more strictly. This ensures a fallback value is used when alias is missing or empty, like handling empty strings, which improves consistency and prevents alias display issues.
