Transform Node, Frustration - can someone help please ?

I've created a composition depicting an aerial view of Prague, incorporating various elements such as animations, text, pictures, and videos.

The setup is as follows:
Over 300 nodes > Transorm > Media Out

However, I'm encountering an issue with achieving smooth movement using the transform node. Essentially, I aim to zoom or move to specific points at certain times, pause for a few seconds (or move slowly along a path), then transition to other points, repeating this process about 20 times.

Issue 1:
When I keyframe the center (both X and Y), setting keyframes at, for instance, frames 0, 100, and 200, everything appears fine initially. However, if I later decide to modify the X-coordinate at a middle frame, the Y-coordinate also changes, leading to a drifting effect. This seems to occur with every second keyframe.

In essence, why does adjusting X affect Y, and vice versa?

I attempted to address this by right-clicking on the center and modifying it with an XY path, which solves the issue to some extent. But then we encounter the next problem...

Issue 2:
With the XY path implemented, everything operates smoothly. However, when attempting to add smoothness or easing to the movement by using the spline panel and adjusting both X and Y, the result is erratic movement.

So what can I do ? Anyone ? I am stuck with this for over 30 hours

Oh well.

Just uploaded an video about the issue here:

As per audio quality and so, my apologies, but I am tired and recording just on some headset.

The transform nodes follows ( even though, I had the issue with transform node in a new project, with empty BG )
