Highlighted outputs in PURE Portal Edited

[Marie_Mallon]

A member of staff has highlighted five research outputs in his pure profile but only one is appearing in his profile in the portal.  He has also added quite a bit of information in his Biography, Research and Teaching interests.  Could the four outputs be missing due to a limited amount of space being allocated in the portal?  Has anyone else found this issue and if so is there anything can be done apart from removing some information from other areas?

UPDATE 27 Jan 2020

I asked the member of staff to remove some of the content from his PURE Profile and see if this would allow his five highlighted outputs to appear but unfortunately it has not made any difference.
