Finding Next TRUE Value?

I'm currently using a formula which is exactly what i want but i need it to do something additional.

The formula is: =IF(ISNUMBER(SEARCH("Level 1 ",$I:$I)),$K:$K,"")

My understanding of this formula is that the cell the formula is in then searches column I for the value "Level 1 ", if it's true it returns what is in column K, if false then it returns the cell blank/0. This is a great function and works well.

What i want to know, is there a way to add another rule on to it that instead of returning the value blank/0, it finds the next cell in the column that has a TRUE value and omits it instead.

For example:
At the moment it shows:
Level 1A
Level 1B
Level 1C
(Blank Cell)
Level 1D
(Blank Cell)
Level 1E

But i want it to show like this:
Level 1A
Level 1B
Level 1C
Level 1D (Replaces blank cell with the next TRUE value)
Level 1E (Replaces cell that previously had "Level 1D" in it to the next TRUE value seeing as "Level 1D" is now above)

I don't want the cell to appear as blank.

In column K, i would only have the data for "Level 1 ", i can then copy the formula to other columns for "Level 2 " and so on. I don't need it to return the cells in alphabetical order, just the next true value in the column that matches the values in the reference column.
