Link problem in Multiple site using Single Admin

I have created multiple site in single admin.
site one->abc.com/siteone/
site two->abc.com/sitetwo/
site three->abc.com/sitethree/
When i am creating a link through content block in abc.com/siteone/ from abc.com/siteone/sitefinity/ admin, the link is created with
<a href="/siteone/link1s" sfref="[pages]7a2cc6e6-65ce-4319-8423-15b3032a4026">link1</a> it is fine.

If i am creating a link through content block in abc.com/siteone/ from abc.com/sitetwo/sitefinity/ admin, the link is created with <a href="/sitetwo/healthcareprofessionals" sfref="[pages]7a2cc6e6-65ce-4319-8423-15b3032a4026">HealthcareProfessionals</a>

but it should be <a href="/abc.com/siteone/healthcareprofessionals" sfref="[pages]7a2cc6e6-65ce-4319-8423-15b3032a4026">HealthcareProfessionals</a>

Please guide me how to solve the issue.

Thanks & Regards,
