replay missing preceeding days

[ATI user]

I am trying to replay NQ 06-12 contract from the first to the last day.
I downloaded the data months ago, including sundays, and have replayed it many times in the past without a problem

today I replayed mar 8 and 9 without a problem
12 mar also replays properly with sunday 11 mar data as the prior day as it be
however, when I try to replay mar 13 or 14 or 15 or 16 each of them starts with sunday 11 mar as the immediately preceding day...i.e. all days between sunday and the replay date are missing

I tried DB repair and reset and restarted NT and nothing corrects the problem....
I downloaded the data for the week again and same problem exists

using the replay slider to select 930 am open, all bars exist for the replay date however all bars between sunday midnight and the replay date midnight are missing

changing session template to default 24/7 (as in attached pic) makes no difference

ATI user,

Market replay uses a combination of historical / replay data and it sounds like you're missing the historical data for this section. It's going to load historical data for all dates earlier than the "From" date that's selected when you first connect. If you have this data available through your data service, you should be able to download it and it will then fill in the gap that's seen during replay playback.

I tested for the following week which was ok...then went back to problem week and it was ok

suspect issue was chart initially was loading 22 days...which from first day of a contract may have caused the issue....after switching chart to 8 days and going forward a week and back a week, problem resolved itself
