Custom parameter scale for instance generation

Glyphs
1

I generated the heavy instance by extrapolation and applied:
CUSTOM PARAMETER: Filter >>Transformations;ScaleX:102;ScaleY:102
Some glyphs fly on baseline like “i” and other like “n” down on it.
Is possible that I’m doing something wrong?

Thanks in advance,
Eduardo

Can you send me the font file?
