Links for classes in other namespaces aren't automatically generated

**Operating System**: Windows

**DocFX Version Used**: 2.58.9

**Template used**: default

**Steps to Reproduce**:

N/A

**Expected Behavior**:

Link to the respective class page every time that I use this class in another class

**Actual Behavior**:

Sometimes they link sometimes don't

If I have a class A and B in namespace First and a class C in namespace Second. When I ref C in some A/B methods, this does not generate the link to the C HTML page, this works with some classes but not with all. So I came here to ask what I need to have to make sure that those automatically links will be generated
