Hi.
I’ve not made our clients webpage but are maintaining it. Now after some updates the certain fields add markings “by themselves”. For example in nettopaino -field there’s a extra letter g and package field adds kpl -extract. Where does those come from as in the other fields there isn’t any problems?
I would check where the field is spit out, like the block or template or page builder component or however that section is built and see if extra markup is there. ACF doesn’t add anything extra to fields.
