Thermostat says cooling but stuck on the same temp for hours

[m3ganlove]

I just installed my nest 3rd gen learning thermostat yesterday. There is only four wires: Y, G, W, R (jumper to RC) on the original thermostat pictured here: https://ibb.co/nspF3nC

here's what it currently shows on the nest: https://ibb.co/rmPQ4Yx

I can't tell what exactly is wrong. There was a low battery issue last night but now it seems to be fine, connected to wifi and all so I am not sure it's about my C-wire although it may possibly be. 

Our HVAC system is ancient to be honest with you, and this is what the control board looks like. C seems to be wired but not Y so I'm guessing that is where the cooling issue is happening? https://ibb.co/XSPCmtW

Would appreciate any help! I don't want to spent another sweaty night here in Texas now that the temp is going up!
