Yoast – Space in Sitename

hope someone can help. For some strange reason Yoast keeps adding a space in sitename for some of my pages. So the sitename is “naturalbodymindspirit” but Yoast adds space so that title becomes “naturalbodymind spirit”. I tried forcing title rewrite setting but that didn’t work. Again for some pages it displays the sitename correctly but for others I get the space. Any ideas on how to fix? Thanks in advance.
