remove double titles on y-axis with two gaps - gg.gap

Hi there,
I used this mod of gg.gap:
https://community.rstudio.com/t/y-axis-break-with-gg-gap/84271

It work's perfectly, but now I need to have two gaps. Is there a possibility to also remove the second title (see png "Verteilung" between y-axis 15/400)

Thanks for your help
