Upgrade MongoDB Deployment Replicaset 4.0 to 4.2

Hello Team,

We did Create a MongoDB Deployment using Ops manager with version of 4.0.13 (with backups Enabled).
Now We are Planning to Upgrade the Deployment to 4.2.24 Version.

When I try to Upgrade using OpsManager (by Changing Version ) to 4.2.24 I am seeing the Below Error

Invalid config: No additional changes are allowed when updating major or minor version number. Detected the following change: PROCESS parameter net.tls.certificateKeyFilePassword changed from ******** to ******** (On the Ops manager). I am 100% positive that I am not changing the certificatkeyFilePassword .

How Can I resolve this issue?

Also, I am seeing this POP up in the Ops Manager for this Deployment.
