Lose information(fields) in Strapi everyday

Hello colleagues,
is it possible someone to help me with a very weird problem. Everyday when i open the Strapi and check let’s say for example table Products inside i have field “keywords” etc. but when i come back more than 6th hours this field isn’t presented in the Strapi Schema. I am using g-cloud for hosting, postgre SQL 12, strapi 3.5.3 and node_version 14.19
