Tapping on contact won't show details

Hello, I have an Xperia E.

I wanted to filter my contacts so I could delete the ones that were imported as "Sim Contacts".

After I did that, and switching the filter back to "Phone Contacts", I am not able to access the contact's details, as in diffirent calling numbers, e-mails, etc.

I tap the name in the list, and NOTHING happens.

I 've deleted and imported my contacts several times, but no avail.

I can't seem to find a solution online. Any ideas?
