Had same issue, found a fix on the prestashop forums

in your php.ini file try increasing max_input_vars to more than it is now.

Increased mine to 1500 and it fixed it.

Not sure if this helps you, but on prestashop forum more people had success with this.

We recommend to set 20000 : https://devdocs.prestashop.com/1.7/scale/optimizations/

memory_limit = 128M
max_execution_time = 300;
max_input_time = -1;
post_max_size = 25M;
upload_max_filesize = 20M;
max_input_vars = 10000;
suhosin.get.max_vars = 10000;
