Hello,
The problem you mentioned above is abnormal, I suggest you check these:
1) You are using the latest version of Types plugin in your website, you can download it here:
https://toolset.com/account/downloads/
If you are using some old version of Types plugin, that will conduct some unexpected result, I suggest you remove the old version of Types plugin, and upload the latest version, then update Toolset plugins again
2) In case it is a compatibility problem, please deactivate other plugins, and switch to wordpress default theme 2019, and test again
