The words "unlike" and "unlike" are spelled differently because they refer to different parts of speech. The correctness of their spelling should be checked by the context in which "in contrast" manifests itself as a derivative preposition, and "in contrast" is a combination of a simple preposition with a noun.
The derived preposition " unlike" is formed by combining a simple prepositioninand a nouncontrast, used in the nominative case.
The preposition "unlike" is used to refer to a specific object, phenomenon or person when comparing it with something or someone. In speech constructions, the preposition "unlike" is used with the preposition "from":
Unlikeother citrus fruits, grapefruit has a bitter taste;
Unlike rain, snow fell here infrequently;
Unlikeher sister, she was serious beyond her years.
Combinations with the preposition “unlike” can be isolated members of the sentence if there is an intonation of isolation:
With Petrov , unlike Sidorov, had to be considered.
The weather,unlike the forecast, was calm and clear.
The preposition "unlike" is not an independent member of the sentence.

It's all aboutin contrast toparts of speech. (What's the matter?)

A definition can be inserted between the preposition and the noun:

In the sentence, the noun with the preposition в acts as a complement:
Problem(what?)in contrast to our positions.
