Did anyone saw weird thing that values from form is recorde twice, one after another. Happens on different type of fields (text, select-dynamic).
Ex. Text field "price_eur" (storage: Standard->Article) in DB it writes in price_eur column. First time value 899, records nicely. When I reopen form, it shows up 899 as it should be, then i delete this value and write new one 765, In DB now I have for this field value 765899. What could be wrong.
For select multiple I have the same problem.
In general, when changing value, old values in DB are not removed.
Already made check-ins for DB, cleared caches in browser, page. In database optimisation is made
