Issues when using MLT as a clip in a timeline

Shotcut 24.04.28
Windows 11 Home

If you load MLT as a track into shotcut, then the filters that were on the output track will be duplicated several times. To understand what I mean, I made a video.

I found another error.
If you leave one filter, everything is displayed correctly in the player, but after rendering the filter will be duplicated. If you remove all filters, the player will think that there are no effects and will display them without them, but during rendering the effect will still be visible on the output channel.

If you place an MLT file on the timeline and apply ANY gpu filter, the application crashes.
