I have absolutely no idea what I did to convinve the game. I think I did this:
EDIT: deleted, I found out how to manage it
:
You select your character and select the first type so, that you can select a 2nd type, too.
3. I don't know if you have to select a character from the now shown filter, but if you go now to ship selection you can still change this 2nd type button
I thought it would be more complicated to reproduce that 
EDIT II: It seems that the game sometimes notices that you shouldn't select better than tier 6 ships, I couldn't select any higher classes then 6, even I had warships selected. BUT I typed in "First Class" and suddenly I could switch through all ships again. I noticed also, that all filters won't work anymore if you break it.
Is the tailor's shop maybe intended to open a new interface, similar to the character selection one? I could imagine that the game would have a problem with that.
