ETH balance not showing up in MEW

I am new here and fairly new to crypto. I have an ETH balance in my Metamask wallet and it also shows my balance when I check Ethplorer, but my ETH balance in MEW shows zero ETH. A couple weeks ago I noticed the discrepancy, but just in case there was something being done on the site such as some kind of maintenance, I waited a while and checked again today. All my other tokens appear except for ETH. Anyone have an idea why this might be happening? Thank you in advance.
