Base pass take too much but actually not

I have a problem with the base pass, as you can see it take 8ms but actually is almost empty, is like delayed or the varius pass are distant from each others.
How I’m supposed to fix this?If I zoom on the profiling I can see like black space between the others pass, is this normal or I m doing something wrong?It could be due to my hardware?

As said base pass should take like 0,05 but take like 8ms and is empty
