I double checked the ctselect tool. There is in fact no problem, it’s just that the information in the log file is not correct. The reason is that the time intervals do not overlap with the specified time range; your specified time range selects events from observations 110456 - 110512 which seem not to be included into your run (at least not in the log file).

I changed the ctselect output to be more explicit:
