GUI Bug - Grid Limit Units

[kjs55]

Sorry, I don't have time to do a detailed bug report. If you cannot reproduce this, please add a comment and I'll add more details.

v7 & v8: Activate Power Factor on PF tab of Energy Management. Then go to next tab Grid Limit and activate w/ Apparent Power basis. You'll see the units of Grid Limit change from MW to MVA. Now return to PF tab and deactivate it. Now return to Grid Limit tab. Units of Grid Limit remain as MVA instead of changing back to MW.
