Absolute nonsense; Levels 4, 5 and 6 are all acceptable.
The OP doesn't state if he the English Proficiency is the default Level 4 that was given to all JAR holders, a Level 6 given by an examiner etc. I was implying that the default Level 4 is no longer valid.
There are people saying to send in English Proficiency as evidence of radio navigation training (WTF?) and you decide to pick up on minor technical wording. Lol
