@satianv I remember I had the same problem. The database tools files linked above have a problem that the KD screen widgets are not aligned properly due I believe to a bug in the SambaPOS version that was used at the time to export them. I fixed it myself before and have exported fixed DB tools files - they are identical in every way to the original - please use these below, they should work:
