FortiWeb: Web Interface not loading properly after firmware update

Hello friends, after updating the firmware to version 7.2.7, we got a problem that some interface elements are not displayed properly, for example, instead of some active lists and tables, we see the names of the elements - ip_group.detail, menu.prot_threat_score_profile, client_manage.risk_level_values_threat_weight, etc.
Rolling back to the previous firmware version did not help, the problem persisted. Is there any way to solve the problem?
