Unable to change parameters for a subset of tools

For multiple tools including Trim leading or trailing characters, Trim sequences, etc, I am unable to change the default parameters. If I input a different parameter, running the tool will reset to the default parameter. Over a month ago, these parameters could be changed.

Curiously, I also have saved workflows from over a month ago, where I have altered parameters for these tools and can still successfully use the saved parameters. Now, however, I am unable to change the saved parameters in the workflow to a different parameter - even after re-saving the workflow. It just resets to the previously saved parameter for that tool.
