Not all entries shown in CSV exported file with flamingo

Hello,

I’m Simone and I’m using CF7 and Flamingo for long time with no issues since today:
I’d just like to know if there is someone who encountered the same problem:

I have an application form in 3 different languages in a music academy web site for participation in master classes, these forms are active for 2 months. if I export all the messages in a single csv file there are some entries that are not shown in the file (in the email notification everything is ok), while if I export the each list for each language everything is ok. Last year, when I did the the same there was no problem for that.

Could it due to the new wp version? Is there a tip to fix this problem?

Thanks in advance.

Simone
