Dear @clmntmcht,

Thank you for your reply.

I want to mention, that there may be a limitation set by the Server.
So, please get in touch with your Hosting Provider and ask them to expand the following PHP values or do it on your own via the cPanel. 

max_input_vars 20000
max_execution_time 600
max_input_time 600
post_max_size 256 

Please expand the values, check the case again, and let us know whether the problem has been fixed or not.

Thank you.
