Clear calibration during process doesn't delete old data

Question

Hi, 
 
 I try to understand why I have old injections data for only some of my target calibrated compounds and other are ok. I have no idea. 
 
 First here how I usually proceed to my calibration with bracketing mode at "none".

When I check the curve, the majority of my 30 calibrated compounds have one calibration point like it is supposed to be, but some have old or more recent injection data when we look at those curve points. 
 
 How can this happen? How can this only happen to some of my compounds. 
 
 The majority of them are ok with one point only. 
 
 THank you for your help.

Hi Martin. I confirmed that I used 1 level calibration. 
 I used Curve calculation at "From average per level" because my internal standard are in each of the 4 standard solutions. 
 Every other compounds are there only once so I must be a one point curve to all. 
 I don't know why some compounds (maybe 6-8 compounds) had curve points from another injection date. 
 I will open a call with Agilent Canada or you think you understand the situation ? 
 Here is another example today about another process. You can see that Chlorobenzene-EIC has 3 calibration curve points for unknown reason. 
 
 Thank you again for your help. 
 
 I tried to delete manually all the curve points that it is not OK, but I can't in the Bracketing mode "Overall". I will try to "none" mode.

Hi Martin, Is it possible that I have another problem related to our 2.7 update. I can't show the acquisition anymore on my report template and in the past it went well.

Thank you for your help.
