TALP backend with a ProperlyNested code does not behave properly.

In a Fortran code that I know is ProperlyNested, I want to use TALP to get some profiled regions, but I'm getting some warnings/erros in the execution and at the end, the regions are created in the .csv but all of them with 0 value.

I'm initializing Nesmik with:

call init("ProperlyNested", "env")

Before the execution I'm selecting the backend with:

export NESMIK_BACKEND="TALP"

And inside the execution log I have this:

...
ProperlyNestedBackend:env                                                       
Selecting nesting mode to: assume properly nested behavior                      
Could not find a matching properly nested backend with nameTALP skipping.
No ProperlyNested backend found, proceeding with Not Properly Nested Backend
nesmik::TALP init()
Calling region_stop_last() is not supported in NotProperlyNested Backends
...

Any hint on this?
