CFDB suddenly won’t export all forms! HELP!

Hello,
I’m hoping someone can help, as I’m desperate: My company has used contact form 7 with CFDB for years. CFDB is how we have exported our monthly form data into excel. It has always worked no problem. Suddenly, after updating my WP version last week, it will no longer export multiple forms data at one time! We have over 200 forms, with a lot of submissions coming in each day, so pulling these by individual form is impossible!
Can someone please please help!
Here is how we have been doing it up to this point (per Michael’s original instructions):
Go to the CFDB Shortcode page

Select Export tab

Select from Export File

Go to From tab

Select the last in the list, * All Forms *

Go to Rows tab

In the filter expression field, you can just type in something like:
submit_time>August 1, 2018&&submit_time<September 1, 2018 which would give you entries for August (note you should choose your end date as the day AFTER you want data for. So if I want up to the 15th, I need to choose the 16th as my end date).

click the link that is generated for you in yellow under Generated Export Link
. An export file should download.

Thanks in advance for any suggestions you may have to get us working again.
