Tabularx adding rows makes table disappear and wrong margin

The following MWE shows how you could minimize the amount of wasted white space in your table while keeping the width of the first column roughly at 1/3 of the total width. If you prefer the approach using two X type columns, make sure that the values of hsize add up to 2. Alternatively, you could also use a p type column for the first column and let latex calculate the required width of the second column, which should be easier than the approach using two X type columns.
