The data is there, but it's out of sight because of the blank rows that are included due to the use of whole columns (A2:B). Filter the rows where A or B cells are not empty. One way to do that is by using QUERY(), i.e.:
=QUERY({{'source data 1'!A2:B};{'source data 2'!A2:B}},
"Select Col1,Col2 Where (Col1<>'' OR Col2<>'') Order by Col1",0)
Older post, but I wrote a single-cell array formula that accomplishes this task and placed it into your editable sheet, in a new sheet I created for the purpose (Sheet2).
Headers are manually entered in Sheet2!A1:E1.
The following array formula is entered into Sheet2!A2:
=ArrayFormula(IF(ROW(Sheet1!A2:A)>COUNTA(Sheet1!A2:A)*18+1,"",{VLOOKUP(Sheet1!A$1,TRANSPOSE(QUERY({Sheet1!A:AM})),INT((ROW(Sheet1!A2:A)-2)/18)+2,FALSE),VLOOKUP(VLOOKUP(Sheet1!A$1,TRANSPOSE(QUERY({Sheet1!A:AM})),INT((ROW(Sheet1!A2:A)-2)/18)+2,FALSE),Sheet1!A2:AM,{2,3},FALSE),VLOOKUP(VLOOKUP(Sheet1!A$1,TRANSPOSE(QUERY({Sheet1!A:AM})),INT((ROW(Sheet1!A2:A)-2)/18)+2,FALSE),Sheet1!A2:AM,MOD(ROW(Sheet1!A2:A)-2,18)+4,FALSE),VLOOKUP(VLOOKUP(Sheet1!A$1,TRANSPOSE(QUERY({Sheet1!A:AM})),INT((ROW(Sheet1!A2:A)-2)/18)+2,FALSE),Sheet1!A2:AM,MOD(ROW(Sheet1!A2:A)-2,18)+22,FALSE)}))

To accomplish this you just need to use an arrayformula:
A word of caution, always delete excess rows in your spreadsheet, in your example you are only using 10 rows of data but your spreadsheet has 1,000 rows, make sure to delete those excess rows so you only have the amount of rows you actually need as using an arrayformula like this will have to calculate every row even though it assigns the rest blank.
