This is due to the title structure at Otto, which is often a bit confusing. The title is made up as follows:
The first part is the title. Here the character limit is 70 characters. Otto then automatically inserts the values from the light gray fields, which can vary depending on the category, and finally the "special features" field is inserted. In the example "made from recycled material" here you have another 170 additional characters. All together this results in a title that has more than 70 characters in the buyer view. We are already working on a small feature that will show you a title preview in the app so that you can see the entire title as it will later look on Otto. Unfortunately, however, the title must be created using the above-mentioned fields with the respective character distribution. So feel free to add the optional field "special features" under Fieldsettings to be able to use more characters for the title.
