Hi
The most likely cause is you are running an older build of MT4. The latest build is 1170 (20 Dec 2018) - click Help and then About to check the build number.
If you close and reopen your MT4 platform it should update automatically. If it does not, it is possible your broker does not offer the latest build (they really should do so) in which case you can seek an update from MetaQuotes by going to the Accounts tab and setting up a demo account with MetaQuotes. Once you open this your platform should update automatically, although a restart of the platform will be necessary.
I hope that helps.
A temporary solution that may get you round you specific issue (although you will have to do this every time you upload an EA) is to modify it within the MT4 editor by finding any reference to TesterHideIndicator and change this to HideTestIndicator which is what previous builds used.
