Does sequence number 3 display in the portal when the filter condition is removed?
Also- maybe check to be sure that this is not a refreshing issue by creating a button that runs a simple one line script the with the script step: refresh window. Make sure to check "Flush cached join results."http://www.filemaker.com/help/11/fmp/html/scripts_ref2.37.9.html
If by chance this is your problem and you'll be deploying on a wan, you'll want to be sure to google/research the methods for updating filtered portals without using the 'flush cached join results' which can have a negative impact on network performance.
PutonITP is formatted as a check box. I suggest inspecting the value in this field for this record by using a copy of the field formatted as an edit box after clicking into that edit box. It's possible that this field has Yes on one row and some other value on a second row of text in the same field. In which case, it will not pass the filter specified and will be omitted from the portal.
