Display of "Title" of a contact

Hi folks,

All contact are nicely synchronized with my Android phone except for "Title".

On my phone the title shows the rather ugly code set in dictionary, e.g. MME, MLE or MTRE instead of e.g. Mr.

Also, if I create a new contact on my phone and I set the title to "M.", then it is ignored by Dolibarr and the entry is not picked up.

How can I fix this?

Kind regards,
Roman
