Problem with changing existing template in Zabbix 6+

Hello!

I can't change some template parameters on the host. For example, by default, all network templates read information in the interval of 1 time in 3 minutes. I wanted to change this setting to 1 minute. I enter data "1m" - update. The data is not saved and reset to "3m". And even with new hosts it is not possible to change templates. Zabbix 6.0.4 and 6.0.5. Mysql 8, php 7.4.

There was no such problem on the previous version 5+. Thanks!
