These two transitions have a pretty major flaw - they're not instant. For example, when I place Slide Right on a clip, that clip should INSTANTLY start sliding to the right at a consistent speed and then reach the end. Instead, well, it'll make more sense if I show you. A good example of what I mean is the project I'm working on right now.
Here's a timestamp to a video's intro (not my project):

Pay close attention to how the text slides into place.
I have 1:1 recreated this style of editing (I'm friends with this content creator and I've volunteered to edit his next video), using the same song, transition start points, transition end points, and everything, and I've used both "Slide Right" and "Slide Left" to accomplish this:

However, you'll notice one difference in my version - the text transitions, specifically that they're slightly delayed and that it's really fast. I have direct confirmation from him that like my recreation uses the same transition and the same transition length.
This issue is more complicated than just that, and it's much easier to see and explain if the transition is used on a longer clip. In this second example, I use the same Slide Right and Slide Left transitions, but instead make the transitions last 4 whole seconds:

Nothing appears to be wrong... until you watch this screen recording of me pressing Play in the editor:

The problem is now abundantly clear - the actual effects visual effects of the transition - the text actually starting to slide to the right or left - only start when the playhead has reached the last 20% of the transition's length.
This is true regardless of the transition's length, which is painfully clear when you look at both of my examples.
In the first example, the lenth of each transition was a half of a second, but the actual effects of the "Slide Right" and "Slide Left" started playing when the transition was 80% over, causing the actual sliding of the text to take a few milliseconds instead of the whole half-second.
In the second example, the length of each transition was 4 seconds, but the actual effects of the "Slide Right" and "Slide Left" started playing when the transition was 80% over, causing the actual sliding of the text to take just under 1 second instead of the whole 4 seconds.
Here's a visual representation of how these are supposed to work:

But here's a visual representation of they actually work:

Additionally, despite NOT using the ones labelled "Slide Right - Elastic" and "Slide Left - Elastic", these have the added effect of "snapping into place" which is not part of the intended effects. The accurate name for these four transitions are:
Slide Right - Elastic
Slide Right - Slightly Less Elastic
Slide Left - Elastic
Slide Left - Slightly Less Elastic
This fatal flaw makes my edit - and by extension all sliding edits - impossible, and I'd like a solution or a workaround if possible.
