When I write out 15 IPTC tags (index 0-14) and the data for one of these tags is empty the data returned in a subsequent read is shifted out of sequence.

ie. I store image data in these tags and have done since ver 2.0 and now when I try and retrieve that data from the tag as below, I get an error because this is now receiving data from tag 5 if tag 3 was blank.

What is actually received is 0,1,2,4,5 (as far as stored data goes)

Convert.ToSingle(iptcData[iptcData.IndexOf(iptcData.LookupTag(174, 4))].Data)

Was this a deliberate change or a bug?

If it was a breaking change then how do we now fetch the original stored index with the data?
