I am having trouble editing text in a custom sheet format created in Solidworks 2018 SP4. After entering a note in Sheet Format it cannot be edited. After exiting sheet format the text disappears. You can get it to re-apear by cycling the layer for the text off then back on or by changing the line weight of that layer. However, once its entered the text can no longer be selected or edited or deleted. I've uploaded screen shots and a copy of the offending drawing template file. Does anybody have any ideas on how to fix it so I can edit the text?
