Hyphenation in Swedish adds letters
The Swedish word "mässing" is given a third "s" when hyphenated (mäss-sing). InDesign 15.0, MacOSX 10.14.6 (18G95).
I have a similar problem with every hyphenation in all foreign languages - additionally to German (mother tongue) I create my documents in French, Nederlands, Spanish and Czech. When the text has the country-specific spellchecking (e.g. French text with French spellchecking) the result in the PDF are different letters (not always the same) "above" the hyphenation - see attachment.
Workaround: I give all my foreign language texts the German spellchecking. Problem with this - of course: the hyphenations are at the wrong place.
