Upper layer punch through artifact

Hi there, Bambu Studio generates a strange artifact that punch through the layer above. Picures may help explaining the problem better.
This is what I wish to print:

The base is 4 layers high (0.8mm), the flash symbol starts at layer 5 (1.0mm). It appears that the flash symbol somehow punches through to layer 4. So this is what the sliced model looks like.

Layer 3 (OK):

Layer 4 (Artifact):

Layer 5 (OK):

These are the settings I changed in the slicer:

Any clues what could cause this? Thank you
