Galmar Stone-Fist never greets the player with the "Stormblade." dialogue once the player is promoted to Stormblade. This is because the line of dialogue requires that the player is in both the Imperial and Stormcloak factions when it should only be checking that the player is in the Stormcloak faction. The solution to this would be to delete the "Subject.GetVMQuestVariable(CW [QUST:00019E53], ::playerAllegiance_var) = CWImperial [GLOB:00073F10]" condition check from (0005B404) in "CWDialogueHellos" in the "CWDialogue quest".
There is also another "Stormblade!" greeting that Galmar says (although the audio is slightly different) without any problems because it doesn't have that condition check on it. The ID for that line is (00083256) which has the line shared with another voice type. Legate Rikke also has a similar setup for her "Legate." (0005B3C9) and (00083248) lines, but her lines are both setup correctly and don't need fixing.
