Problem with de metamask extension (pc). Balance not update

When I connect my metamask extension (pc) the balance of hours ago appears, not the actual current balance. It does not update the actual value. When I connect on my cell phone the correct balance appears, and i can do all i want. Everything is OK. Why is this happening? I can’t even do any transactions on the pc extension, because the balance on this metamask (pc) is not the real one. how to solve this? I tried to clear cache, it didn’t solve it. I installed and uninstalled the metamask, nothing. What to do?
