Nested sequences are automatically un-nesting

[yoavp94359601]

I work with nested sequences a lot, and now, all of a sudden, Premiere seems to be refusing to allow me to bring any sequences into the Timeline as nested sequences. Usually, I can drag sequences from the Project window to the Timeline and get a nested sequence in the Timeline, but now it won't "drop" into the Timeline. If I instead load a sequence into the Source window and try to edit it into the Timeline as a clip, the sequence automatically "unpacks" into individual clips when it comes in. This is true of Photoshop files I imported as layered sequences as well as normal video sequences created in Premiere. It's a weird and sudden behavior change and I cannot figure out why. Please help!

Thank you! That's it!

thanks for that, 

I work a lot with a one long master sequence of several hours and use it to strip child export sequences out of it.

My preferences had reset and I couldn't find the function. auto nesting was driving me nuts because in my case any change in master would update to all childs. 

additional keyword: nest un-nest, unnest,  source sequence to block . insert and overwrite sequences as nests or individual clips.

thanks
