Explain at least two preview issues in update set

[Tejas16]

When the update set is loaded into another instance and when click on preview button then sometimes update set preview problems are occurred in (update set preview problems)  related list?

Hi Tejas,

It means section like below for example is latest one in your instance, to elaborate if you see my Related Records section if someone has added one field in test and I have made changes to section in dev so when I move my changes to test it will throw me an error what you are seeing now so just compare the accept or reject based on your thoughts.
