Title case change not available

I used the Zotero connector to save this item in Zotero.
It creates a Journal Article (it does not really matter here), but what is puzzling me it that the case of the title cannot be changed. The options are not available. Is there any reason for this? Or am I missing something obvious?

The title created during the import is NUMERICAL ANALYSIS of OF NONLINEAR EQUATIONS
