Code Coverage tab missing on Ant + JaCoCo import

We have an Ant build that constructs a second artifact, each of them generates a JaCoCo exec file.

We also have a service message sent to TeamCity to import both JaCoCo files, which works correctly, as I can see a Code Coverage section on every buid overview.

However, Coverage tab is not showing so there is no detail about coverage stats.

Can you please help me on setting this up? Is it possible to show Coverage tab when importing JaCoCo execs?
