This is a common error in the tester, I'd like to see what the mql4.com community says about this - there are ways a strategy can create this by having too large lot size, but is there anything with the tester or data that could cause this due to some parameter in the strategy that would NOT be a mistaken lot size ? ( such as an error in the data or tester) ?

This has nothing to do with lot size or the strategy. It's the same as all 'unmatched data errors', only in this case the volume is unmatched (usually O/C/H/L are unmatched). It means the tester is using data from a lower timeframe to test the EA on a larger timeframe, but the volume in the larger timeframe is not the sum of volumes of the lower timeframes... Hence - unmatched data error - this is literally the problem.
To solve this problem, build all larger timeframes from M1 data using the standard period_converter script. Please search for more info (this error and it's solution have been discussed many times).
