Inner walls on top layer

[PolDan]

I’m making a keychain, there is a base of one color and on top of it there is a text of one other color and of 1 layer only

On the top layer of the base, bambustudio generate some inner walls following the trace of the text layer above

This makes the print of the top layer of the base very slow and with some artifact..

The print is not straight, is it possible to avoid the generation of those inner walls, and have a straight top layer of the base?

try increasing top shell layers

With a modifier on top layer of base with set 1 wall loop, there are not generation of inner walls but only minor artefact of internal solid infill..
