Can't open mapped network drive

Hello,

Well what happens is on My computer i have a mapped drive (P:/NAS) that
is connected to another PC if i double click it it doesn't open says i
don't have enough rights but if I right click it and press either open
or explore it opens fine. what could it be?

PS: I noticed that i have 2 opens when I right click the drive one is
"Open (0)" and the other is normal "Open"

Best Regards
Zain
