I don't know how if it is intentionnal as I missed it for years (maybe because it was only a +1 sword before tob...) but the Flame Tongue doesn't have the +1 fire damage that's included in its description.
Fwiw, EE add it (+1 fire) and mostly keep it as +1 as it should ; BG1 name was Long Sword +1, Flame Tongue.
making it a +4 is a "cool stuff" but not a fix so maybe a fix would be to set it back to 1... as Kondar
