It's a weird bug in my program. it is not possible to set the date range for printing longer than March 8, as soon as I try to extend the printing period to March 9, the program crashes. On the other hand, I can print if I set the date period from March 16 onwards without any problems. There seems to be a problem with the week of March 9-15. All other periods can be set for printing as usual. What could be the problem?
