Sorry to hear of the issue you have encountered while using Moneydance. When Moneydance syncs, all data should be taken from the syncing folder in Dropbox and added to the local data set. Disabling syncing shouldn't result in data loss. It sounds like Moneydance is not correctly incorporating the syncing data into your main data set.
Could you let me know what version of Moneydance you are using? You can check this detail within Moneydance by navigating to Help --> About Moneydance. There have been some improvements made in the syncing mechanism in more recent versions of Moneydance 2017. If you are using an older version of Moneydance, this may explain the strange behaviour you have encountered.
