Maybe because the actual name is &quot;Brötli&quot; and &quot;Zöplfi&quot; coming from the Swiss German naming of small breads. Umlauts are usually converted like so: &quot;ö&quot; to &quot;oe&quot; but not always. So there may be confusion as to if it&#x27;s &quot;brotli&quot; or &quot;broetli&quot;.<p>Then again, this is just some wild speculation. :)
