Did anyone merge Lee Ching(s)?

Has someone recently merged the Lee Ching entries? I went to add him to a cast list and and all except one credit is under Lee Ching (1). There is a single entry for (2), (3) is missing and (4) for another actor.
There are at least two Lee Chings with major list of credits in vol.4 Filmography, that I recall. One is older and the other is younger that I started seeing in late '50s/'60s films. For instance the films with '*' would not have been the same actor in the '30s/'40s.
