Why when you hit "trade" and then stop trading, does the broker update change "Assets.dta" on some of the lot sizes back to micro lot size?

I've re-confirmed that Assets.dta & AssetsFix.dta are set to 100,000 lot size for all currencies, yet system still trades 1000 micro lots real-time. "Contracts per lot" while testing always correctly says 100,000 lot size, but that same system always trades 1000 lots.
I've temporarily set code for "Lots=100;" in the mean time for trading, see if that makes a difference.
