Hi Mohammad,
Thanks for getting back to me.
I have 9 portfolio items and as you will see in the screenshot, there are portfolio items assigned to the 4 designated categories.
Further, when I click view under each, I can see the portfolio items for each category, see links below:
‘Research & Guidance’
‘Restoration & Regeneration’
‘Strategy & Planning’
‘Working with people’
Yet, ‘Working with people’ is the only link that is displayed from the portfolio page.
I hope this helps with working out what’s going on – let me know if you need any further information / screenshots.
