Vlookup_is_Sheet_Corrupted.xlsx

Hello All,

attachment has two sheets. "Incorrect" has a simple Vlookup formula but not giving expected result. Same sheet copied to another sheet it is working perfect. Checked some basics like "Auto Calculate", "Clear Formats" etc. not helping.

is the sheet corrupted, if so any thoughts on what are the common causes of corruption, any ways of resolving?

If not, what am i missing big time !

Thanks
R
