Most likely (no doubt in my mind) that the truss top chord is not designed for the weight placed on it. Engineer should evaluate. Do you know if the dimensional lumber was installed after the building was constructed?

Re: Attic issues
In non-snow load areas, especially prior to the adoption of higher design loading in IBC, it was customary to specify a toe-nailed connection for jack trusses up to about an 8' span. The jacks can be trusses or they can be conventional framing. You can not see the nails from the back side, you would need to see them from the front face. If there are nails then it was probably adequate for the code when it was built.
It's a bit unusual to see 2x6 jack framing with 2x4 trusses, but there's nothing wrong with that. Also note that the flat 2x6 purlin laid on the top is also a customary practice for bracing the flat top chord.
Have a great day.
