Well, i‘m just gonna go with what Airfix provided and trust their research. If you want them gone, you can just sand them.

Anyway, i finished sanding the fuselage- finally! Will rescribe some lines but overall i am happy with it. On to the wings! As i worked on the engine nacelles, i realised another piece was shot, something i did not see when i asked for replacements from Airfix. It’s kind of funny however and i am thinking of leaving it as it is, kind of like a souvenir. Also, it’s not that visible as it will be close to the fuselage.

Nasty gap! I Think You need to make photo and send to Airfix second time.

Finally! Engines mounted, flaps in place and on they are. Just like that the build picks up pace and it’s starting to look like a Liberator. The tailplane rudders will be painted individually, so i am not glueing them on yet.
As for the shot engine nacelles, i inserted tape and might fill it up with putty.
