Running the 5.2-linux-portable build of 2020-09-09. The optional fields tab has 2 columns on the left for data entry and a preview of the entire entry on the right. However, text cannot be entered in the right column and that whole window cannot be expanded to allow data entry.

The attached screen shot illustrates the situation. Notice in the right side window the volume number (8) at the end of the text. That number is not visible in the volume entry field on the right half of the display.

I kept trying to enter the volume and expand that window, but was unsuccessful. I noticed the string of volume numbers in the right side window and hit the delete key until only a single '8' was present.

This situation was in a previous release and fixed. Please fix again.
