I believe this is not a bug but rather the intended behavior. Since
Greek accented capitals are normally used only in titlecase, some font
designers map unaccented glyphs to the corresponding slots, while
contextual rules are used to replace them with accented variants when
followed by a lowercase letter. Thus the capitalization rules in
Greek are handled. Particularly I find this approach too extreme (and
actually wrong), but nevertheless it is quite popular.

Anyway, you can check if this is the case if you type several words
starting from an accented letter (instead of the accented letter alone)
and make sure contextual alternates are enabled.
