Urgent Help Needed: Data Loss After Adding Rows in Ocean IO

Hi, we have a major problem and are urgently looking for help. Over the last 3 days we have been analyzing and categorizing over 800 rows and were tonight ready with 177 rows remaining. We then wanted to add another batch of 25 rows through Ocean IO lookalike search. After doing so and adding them, 90% of the data of the 177 were deleted. We still see the rows because we have 218 in total but they dont contain any company name or adress or description, just some enrichment data through which we cannot comprehend the data. We actually have a deadline tonight to submit the data after all that work. Can somebody help us get it back?
