For some reason when I published the translation, the title is added as 2nd level heading. Can be seen from here https://ms.wikipedia.org/w/index.php?title=Bias_pengesahan&oldid=5650151
Topic on Talk:Content translation/Section translation
@Pginer-WMF: Sorry for ping, please take a look. Same problem also on bnwiki. https://bn.wikipedia.org/w/index.php?title=রাষ্ট্রীয়_জনতা_দল&oldid=6050680 This happens when you create a new article.
There is another problem. When you publish a section, SectionTranslation adds that section title twice, e.g. (notice == মুখ্যমন্ত্রীদের তালিকা == added twice).
Thanks for reporting @Tofeiku and @আফতাবুজ্জামান. This issue is expected to be resolved (more details in this ticket). Please, let us know if you are still experiencing similar issues.
Thanks a lot for your interest in the tool and helping to make it better!
