Executor image versions not synchronised in KNIME Business Hub

Hello everyone, I have an issue. I installed KNIME Business Hub basic plan and initially configured the executor environment using version 5.2.3.

Later, I used the Executor Image Manager to add the 4.7.4 executor image. During this process, it appears that the previously available 5.2.3 executor image definition was replaced or became unavailable in the UI. As a result, only the 4.7.4 image was visible in the selection, and no alternative versions could be chosen.

To recover a newer executor version, I pulled the image from the official KNIME public registry and pushed version 5.8.2 into knime private registry. After doing this, I verified the registry content using:

/v2/knime/knime-lts-full/tags/list

which now returns only:

r-5.8.2-139

At this point, the situation is inconsistent:

• The registry contains only version 5.8.2

• However, the Business Hub UI still displays the 4.7.4 executor image as the available option

• No other executor versions are visible or selectable in the UI

It seems that the executor image definitions in the Business Hub are no longer synchronized with the actual state of the registry, or that the 4.7.4 entry remains stored in the Hub configuration even though its corresponding image is no longer present in the registry.

I would like to understand how I can properly see both versions.
