Imported Gedcom error report

Greetings from Queensland, Australia.

I hope someone can help me.

I exported my family tree from Ancestry.com and imported it into a new legacy file so I could check there were no problems before I imported it into my working fdb of 14000+ individuals.

I have a 35 page error report that I am having trouble translating. My hope is that someone out there can help me understand what it means.

My first example:

Main Record: 0 @R-2140948796@ REPO

Sub Section: 1 RFN online database

* Unrecog. Line for Record: 1 RFN online database

Placed in Note : RFN: RFN online database

Can anyone help? I have 2607 individuals in this tree. How can I work out to which person this record relates? 

Another example:

Main Record: 0 @R-2140948796@ REPO

Sub Section: 1 CALN 0596965 (RG4 4209)

* Unrecog. Line for Record: 1 CALN 0596965 (RG4 4209)

Placed in Note : CALN: CALN 0596965 (RG4 4209)

And another example:

Main Record: 0 @R-2141006709@ REPO

Sub Section: 1 RFN

I haven't been able to find anything online that would help me. I couldn't find anything in the Legacy manual either. Maybe Geoff could do a webinar on the subject.

I have previously imported files into legacy and had no trouble understanding and fixing the problems.

This report has me beaten.

Thank you in anticipation.
