old url still existing after using wp clone plugin

Initaillay I was working on mmab-pcb.com/newsite and installed wp clone plugin by wp academy on it and take the backup. I have to move this website to mmab-pcb.com which is the old one. For this I installed plugin in old website and restore mmab-pcb.com/newsite website through plugin. In this way I moved my website. Now the old website has two languages: English and Svenska. If user enter this url mmab-pcb.com/svenska it will take him to svenska page. But since this belongs to old website and I have replaced old website with new one the link mmab-pcb.com/svenska should not exist as the whole database has been replaced now with the new one. Also the whole old website content should not exist. But if user typed the link mmab-pcb.com/svenska it will take him to the old website. This is very confusing and is not clear to me. Can anybody help me on this.
