After up dating from 2017 to 2018, the part information will not populate correctly, if you enter all the information and save out , when l return to the part the text has vanished!

The only way I can navigate around this problem is to insert text one line at a time, save out , go back in and type next line, save out again, and so on.

This is very tiresome,  as I deal with all lot of individual parts with 12 lines of information a piece. 

I have contacted solidworks with this, but have received no solution, the operator was at a loss, to explain why this was occuring.
