To satisfy your curiosity, here’s my reasoning.
I didn’t report it when I noticed it for Malwarebytes last Christmas because I was busy at the time. It first started for me in November 2019 and largely stopped by April with only one occurrence since then.
I primarily didn’t report it because it just didn’t matter to me once I quickly confirmed that the version change was correctly picked up and the version info was still correct for the major change and minor change numbers #.#, e.g 4.0. I don’t need the additional info provided by a more complete version format #.#.#.#, e.g. 4.0.12.543, which usually represent builds and revisions or maintenance changes.
Also, as shown in the following example of Process Lasso, the chain of version changes is contiguous:

The majority of people don’t usually report problems but I did expect that someone else would eventually report this one. When you did, I gave your post a like because it saved me a little effort.
For the record:
- I haven’t seen any alert with no version information displayed except where there is another reason for the alert such as a security change, e.g.:

- Other programs affected by this on my Windows computer are:
Process Lasso and updater
Service Shell
SRE
