Formatting of services ranks in credits - avoiding a space either side of a /

I'm correcting credits for Pathfinders tt0165053 where the on-screen credits give character names using abbreviated RAF ranks - for example "F/O Jack Chatteris" (F/O = Flying Officer). But IMDB "corrects" this to "F / O Jack Chatteris" with a space either side of the "/". Is there a way of avoiding this formatting problem? I imagine it has been coded to handle the situation where the "/" is used to delimit two character names eg "Jim / Dave" implying that an actor played two characters. But that space is not appropriate in this situation.

So far I have done episodes 1.1 and 1.2 (eg submission 240903-170852-379000). In the past, someone has expanded all/most of the abbreviated ranks but I presume IMDB prefers "transcribe as it is written".
