Why is the block header version value different from the getblocktemplate version value in the bitcoin blockchain?

When looking at block header for block 746632 I see that the version is 1073676292 or 3fff0004 or when reversed 0400ff3f, but the version I received from a getblocktemplate request is 536870912 or 20000000 or when reversed 00000020

My understanding is that the version field can not be different from the one in the block template.
