Text changes when exploded

I imported this text .dwg file into rhino and it came as a block. The issue is that when I explode the block (explode or explodeblock command) the text changes! Anyone knows how to fix this? Thanks

PS: I know I can change this particular text back but I have a file with thousands of text blocks in it and I can’t do it manually one by one

Hi, could you share the file?
Thanks.
